Experienced and professional animal trainer provide their insights in answering this question :
A. First, you should alert your veterinarian of the inappropriate application. Your veterinarian will determine if permethrin poisoning is present.

The following treatment protocol is usually recommended:

1. Decontamination with washing
2. Monitoring of neurologic signs
3. Obtaining access to veins in order to administer necessary fluids or medications
4. Regulation of temperature
5. Stabilization of vital organs

If you accidentally applied dog flea and tick medication to your cat, contact your veterinarian, an emergency veterinarian, or an animal poison control center immediately. The sooner you treat it, the less poisonous it may be and the less expensive it may be to treat.
As there is no antidote, conventional treatment protocols aim at controlling the clinical signs and consist of early control of seizures and tremors, decontamination, and supportive care while the toxins are metabolized and excreted. Benzodiazepines are commonly used to control seizures.
Permethrin poisoning can be fatal to cats. Symptoms include severe muscle tremors and seizures. If you think your cat has ingested permethrin or if it has touched their skin, you will need to seek veterinary attention immediately.
Permethrin is generally used as an insecticide and is found in some flea spot-on products made for dogs, however, for cats, exposure to concentrated permethrin can result in serious illness and death.
K9 Advantix® II also contains the ingredient permethrin, which works similarly to imidacloprid. Permethrin blocks certain chemical messengers in ticks and overwhelms their nervous system, causing paralysis and death. Permethrin is toxic to cats; K9 Advantix® II should never be used in a cat.
When used as directed, such products are safe and effective. However, dogs and cats can easily become sick if too much or the wrong flea product is applied, or the product is ingested post-application.
The onset of clinical signs was usually within a few hours of exposure with some being delayed for 48 hours. Clinical signs may be delayed up to 72 hours post exposure. 1,13 The clinical signs resolved in either recovery or death within 24 to 72 hours, which is consistent with the published literature.
Recovery of Permethrin Poisoning in Cats

The prognosis for a cat with permethrin poisoning is good if the cat is taken for care soon after the exposure. Full recovery can take 3 to 7 days. Education of the pet parent about how to prevent poisoning in the future is an important part of the cat`s care.

The biggest problem for cats is when they are exposed to highly concentrated permethrin products meant for use in dogs, she says. These products may be 45 percent permethrin or higher.
Poisoning symptoms in cats usually occur minutes to hours after exposure to or application of the flea and tick medicine, but may be delayed up to 72 hours. The symptoms typically last two to three days. The most common symptoms of flea and tick medicine poisoning in cats include: Tremors/muscle twitching/trembling.
Acute toxicity: Permethrin is moderately to practically non-toxic via the oral route, with a reported LD50 for technical permethrin in rats of 430 to 4000 mg/kg. Via the dermal route, it is slightly toxic, with a reported dermal LD50 in rats of over 4000 mg/kg, and in rabbits of greater 2000 mg/kg.
If Permethrin is not washed off for a long time or even after 14 hours, it may cause several side effects such as: Mild burning and stinging. Skin swelling. Skin redness.
This reduces the consequences of ticks biting, including skin irritation, tick paralysis and the transmission of diseases. Can I use Advantix™ on my cat? No. Advantix™ is safe for dogs, but it`s very dangerous to cats because of their unique physiology and their inability to metabolize certain compounds.
If an animal is able to lick the product when it is wet on the fur or scratches the area and then licks their foot, the bitter taste of the product can cause the animal to salivate, foam at the mouth, become nauseous or vomit. Also, some cats have been known to become agitated and run around the house.
If you choose to bathe your dog in between treatments, we recommend use of a general grooming shampoo for pets. Do not use K9 Advantix® II on cats. Can I apply K9 Advantix® II more than once a month? A single application of K9 Advantix® II remains effective for four weeks.
Recovery from poisoning in cats depends on timing. The sooner your cat has medical attention, the sooner treatment can begin and the less time the poison has to make its way through your cat`s system. For many cats, those who receive early treatment will return to their normal selves within a short time.
Permethrin is highly toxic to fish and other animals that live in either salt water or fresh water. Permethrin is low in toxicity to birds, but some aerosol products made with permethrin may also contain other ingredients that can harm birds if they inhale it.
Answer: After all surfaces treated with Permethrin SFR 36.8% are completely dry, the dogs can return.
Uncharacteristic sluggishness, unsteady gait, drooling, heavy breathing, diarrhea, seizures, and sudden bouts of vomiting are among the common clinical signs of feline poisoning (toxicosis). A cat owner who observes any of these signs will do an animal a huge favor by seeking emergency veterinary care.
Cats, with their genetically inherited reduced hepatic glucuronidation (Court and Greenblatt, 1997), are less efficient than other mammals at metabolising the chemical, resulting in an accumulation of the active parent insecticide at the sodium channels.
Due to a cat`s altered liver glururonidation metabolism, cats are significantly more sensitive to pyrethrins than dogs. While a precise toxic dose for cats is not well established, products containing greater than a 5-10% concentration of pyrethrins may lead to systemic toxicosis.
While permethrin and pyrethrin are safe for many animals, including dogs, it is highly poisonous to cats. The reason cats are sensitive to these compounds is that they are unable to break down these toxins as they lack the liver enzyme to do so. Instead, the chemical builds up in their bodies causing serious illness.
Insecticides: Insecticides containing organophosphates and carbamates are highly toxic to cats. Signs of ingestion include vomiting, diarrhoea, drooling, muscle tremors and seizures. Insecticides that contain Pyrethrins and pyrethyoids can be toxic to cats too.
Flea and tick medicine poisoning occurs when your cat has a negative reaction to the medication. The chemicals from the medication disrupt the nervous system and can lead to serious health problems. It is usually found in topical medication that is applied to the neck and back.

Relevant Questions and Answers :

the most relevant questions and answers related to your specific issue

Q. Which flea and tick drops are the best and why?
ANSWER : A. Your question is a good one, and unfortunately the answers are going to differ based on who you ask. Many vets are seeing resistance to Frontline, which has been the go-to product for many of us for many years. It contains the active ingredient Fipronil, which is very safe and typically extremely effective. I use it on my dogs and never see fleas or ticks. However other vets will tell you in their areas, for whatever reason, they are seeing fleas and ticks on dogs and cats on which this product was used.

Another reason opinions differ is that some people like to give an oral product, and some like to put a topical product directly on the skin. That’s a matter of personal preference mostly. Bravecto, as mentioned below, is one of those products. Most people find it safe and effective. It uses a different process that Frontline to kill fleas and ticks.

In general the products you buy over-the-counter are likely going to be less expensive and less effective than what you get from a vet. I think the reason is that the more expensive products contain newer insecticides, and likely less resistance to these products has built up in the flea and tick population but also they are maybe less “proven”, so it’s important for a vet to be involved in the use of the product in order to ensure that there won’t be a negative reaction to using it.

If I lived in an area where there was Lyme disease (in the US that’s the northeast and upper midwest) I’d most definitely add a tick collar to my standard oral or topical flea and tick prevention. AND I’d search both of my dogs everyday for ticks. It’s because nothing you buy will be 100% effective, and Lyme disease can be a very serious problem.

If you want to talk further and talk more specifically about where you live and what products you’re considering, I’d be happy to do a consult with you. Nobody here is paid to recommend products, but we do develop preferences based on what we use on our own pets and in our practices.

Q. My cat is excessively scrstching herself., to the point she has sores. She is strictly an indoor cat. Did have flees been treated for 2 months
ANSWER : A. For every flea you see on your pet, there are 100 more in the environment. Get your pet on a good topical or oral flea control through your vet. In flea control, you get what you pay for. Consider asking your vet for a dose of Capstar. It helps get the problem under control by killing the fleas on the pet starting in five minutes but only lasts for 24 hours.

You need to treat your home environment. If you use a pest control service, tell them you are having a flea problem and they can adjust their treatment. Use a premise spray that also contains an IGR, insect growth regulator. This keeps eggs and larvae from maturing into adults and helps break the life cycle. Also, vacuum EVERY DAY, throwing out the bag or emptying the canister every time into an outside receptacle and spraying the contents with insecticide to kill the fleas you’ve vacuumed up.

Treat your yard too, since fleas are opportunistic and will hop a ride into your home on your pant leg without you knowing it. Concentrate on areas under bushes, in the shade. Fleas are less likely to be located in open sunny areas where it gets hot.

If chemicals are a problem, you can use borax. Sprinkle it into rugs, into corners and under furniture, use a broom to work it into the fibers and let it sit for hours, days even. It won’t hurt you or your pet to have it present. Then vacuum it up, reapply as needed. Food grade diatomaceous earth can be gotten from a health food store and worked into the rugs and corners in the same way as borax. These treatments aren’t as fast and effective as chemical insecticides but they can help.

You might want to consider boarding your pet for the day at your vet, to give you the opportunity to flea bomb your house without having to worry about your pet being exposed. They can bathe your pet and give a dose of Capstar while you treat your home.

Be patient, you may have to repeat these steps multiple times 10-14 days apart to help break the flea life cycle.

Skin problems can have a variety of causes, sometimes more than one. It is important to have the problem checked by your vet to determine if there is a medical cause for your pet’s skin issues and treat accordingly.

In pets of all ages, fleas, food allergies and exposure to chemical irritants such as cleaners and soaps can be a cause. Any one of these may not be enough to trigger the breakouts, depending on how sensitive your pet is, but a combination can be enough to start the itch-scratch cycle. Finding out the cause and eliminating it is the best course of action. With flea allergies, if your pet is sensitive enough, a single bite can cause them to break out scratch enough to tear their skin.

Check for fleas with a flea comb. Look for fleas and/or tiny black granules, like coarse black pepper. This is flea feces, consisting of digested, dried blood. You may find tiny white particles, like salt, which are the flea eggs. Applying a good topical monthly flea treatment and aggressively treating your house and yard will help break the flea life cycle.

If you use plastic bowls, this is a possible cause for hair loss, though this tends to be on the chin, where their skin touches the bowl while they eat. If you suspect this to be the culprit, try changing the bowls to glass, metal or ceramic.

Food allergies are often caused by sensitivity to a protein in the food. Hill’s Science Diet offers some non-prescription options for sensitive skin as well as prescription hypoallergenic foods for more severe cases. Royal Canin carries limited protein diets that may also offer some relief. Your vet can recommend a specific diet that will help.

If there is no relief or not enough, consider getting your pet checked by a veterinary dermatologist and having allergy testing done.

Q. Why do cats meow?
ANSWER : A. Cat parents often wish they could better understand what their favorite feline friends want or desire. A cat’s meow can be interpreted in many different ways and can indicate an array of feelings and needs. Here are some of the most common reasons for your cat’s vocalizations:

1. Greeting- Many cats will meow as a greeting when you enter your home or walk into a room. Cats will also meow at another cat or animal in the household to extend a hello and acknowledge the other animal’s presence.

2. Attention – An exuberant meow followed by leg rubbing or another attention seeking behavior may indicate your cat is looking for some quality time spent together. Some petting or rubbing behind the ears may be in order.

3. Hunger – A meowing cat is often a hungry cat. This is one of the most common reasons for a cat to vocalize to their owners. A cat will meow to get your attention at feeding times or even when they want extra food.

4. Sickness – A sick or hurt cat may begin to meow excessively, warranting a visit to the veterinarian. There are numerous reasons for a cat in distress to meow—whether it is related to an upset stomach, an injured leg or a urinary blockage. These meows should be carefully investigated.

5. Entering or leaving – Most cats will vocalize when they want to be let in or out of a room. You may notice when you are in the bathroom or behind the closed door of a room that your cat begins to meow, scratches at the door, and often reaches its paw under the door. This is a clear indication that the cat wants to be where you are.

6. Angry – An agitated cat may meow to warn their owner or another household pet that they are upset and would like to be left alone. This angry meow may increase in sound volume as the cat becomes more stressed or agitated. Often a cat will exhibit this type of meow at the veterinary office when they are unhappy with their examination or restraint.

Each feline is different and so are their vocalizations. Learn to understand the variety of meows your cat uses on a daily basis. This will help you develop a better relationship with your cat and help them live a more trusting and happier life.

Q. Our cat developed a flea allergy in the form of red sores above the eyes Our vet gave him an antibiotic shot and a flea collar but they remain.
ANSWER : A. I’m so sorry to hear! Flea allergies are tough to deal with! Unfortunately when a pet has an allergy to fleas, the problem lies in the flea bite. The actual allergy lies in the flea saliva, so what we really need to prevent is the flea biting our pet! I would recommend a product that can kill the flea before they even have a chance to bite your pet! A couple of really great products on the market right now are Frontline Plus and Revolution. Both are liquid topical products that you place on the skin of your pet once a month. They work by using the skins oils to spread themselves around the body and rest in the hair follicles. Each has a slightly different mechanism of use, but they both work to kill the flea before it actually has a chance to do harm to your cat. Flea collars simply are not as effective. I would also recommend treating your home environment, such as the area where the cat sleeps and the carpets inside your home. Flea eggs and larva can live for a very long time in these environments and unless we treat all of these areas, the problem will remain. I hope this was helpful! Good luck and I hope your kitty feels better!

Q. Why is my son’s cat continually licking her belly to the point the hair is falling out and a sore has developed? She is 12 yrs old inside cat.
ANSWER : A. Many things can cause this such as allergies, auto immune disease,etc. However it could be as simple as your cat is bored or stressed out. Have you had any enviromental changes lately that couild be stressing your feline friend out? Outdoor cats are accustomed to chasing, hunting, and playing with all sorts of critters. Sometimes indoor kitties need added stimulation to keep them “sane”. Try gsetting your cat some toys to play with. A laser pointer can be a great interaction toy for the two of you to play with. You can also try getting your fury friend a scratching post or a cat tower that will allow him/her to sit and look out the window. A good product for stressed out kitties is Feliway. Feliway is a pheremoene that mimics pheromones produced by recent mothers to kittens. This product comes in a plug-in diffuser or a spray and is available over the counter at most animal hospitals. The spray form of Feliway can be particularly usefull to calm kitties who get stressed when put in a cat carrier. Simply spray Feliway in your carrier before you load your cat up. If none of the above has worked it sounds like it is time to use this technique to get yourcat into the carrier and to the vet. There they can perform diagnostics such as skin cytologies, allergy testing, skin scrapes to determine what the problem is.
One thing i forgot to mention at the beginning is you certainly need to rule out fleas as the cause. If a cat has a flea allergy just one flea bite can drive them crazy and cause them to lick thier belly raw and hairless. Revolution is a great monthly topicall product for fleas,heartworms, and intestinal parasites. Even indoor cats need flea protection. Good luck!

Q. I have a pregnant cat and in a couple of weeks my house is getting sprayed to get rid of fleas. But can I put a flea collar on her?
ANSWER : A. It is best NOT to place a flea collar on a pregnant cat as they can cause problems such as deformities or breathing issues to the unborn kittens. If your cat has fleas you may want to check with your vet to see if there is a pregnancy-safe flea product that can be applied, or you may want to use a safe soap such as Dawn to bathe your cat and then use a fine-toothed comb to brush out the dead fleas. Dawn dish soap is very safe on the body and is often used on kittens that are too young for flea medication to suffocate and kill fleas on the body. Cleaning the environment is also a great way to get rid of the fleas, however be sure to keep your cat away from the area that is sprayed if chemicals are used to prevent injury to her or her unborn kittens.

Q. My cat continues to scratch on furniture and carpets. He has plenty of scratching posts around the house. Please help!
ANSWER : A. Scratching is a natural behavior in cats that can be frequently frustrating for pet owners who want to keep their furniture from being shredded on a constant basis. The texture of furniture and carpet is very appealing to cats and this why they frequently choose to spend their time on this activity as opposed to playing with their own cat toys. Here are some suggestions to help curb this unwanted behavior:

1. Purchase a cat scratching post or cat tree that is covered in carpeted or textured material. Place it in an appealing spot that your cat would be inclined to spend time (eg. in the sun). You can also place catnip on the scratching post or cat tree to make your cat even more interested in the new object.

2. You can utilize double sided tape on the ends of the furniture because you cat will not like the sticky feeling and will learn to not scratch in that region. Use the tape that has a lighter adhesive in order to prevent any permanent damage. Other materials, such as aluminum foil or bubble wrap can also be placed on the furniture to discourage the scratching.

3. Keep nails trimmed short by either learning to do this on your own at home or using a veterinary technician, or groomer. Nails can usually be trimmed every 6-8 weeks.

4. Redirect the unwanted behavior. If your cat begins scratching, use a favorite or new toy to distract the cat from the scratching. Give your cat positive praise for not scratching.

5. As a last resort you can use a spray bottle full of water to spritz your cat when he or she is scratching inappropriately at your furniture. Generally, cats do not like water and this will discourage them from continuing the behavior.

Have patience with your cat because it can takes time to understand this is an unwanted behavior and that furniture is not another toy for them to use. You can always consult your veterinary or veterinary behaviorist to help with ideas or further solutions to this problem.

Q. Do natural flea control products work?
ANSWER : A. Although many natural flea control products don’t have to go through EPA-mandated tests, because they aren’t classified as pesticides, this doesn’t mean they don’t work.

There are several natural flea control products that are safe for your home and your pets: repellants, sprays, squeeze-ons, shampoos, flea tags and powder. Also garlic and B-vitamins seem to make blood less attractive to fleas, so many guardians supplement with garlic and brewers yeast during flea season. However, sensitive animals can develop an allergy to brewer’s yeast, so I suggest you monitor your pet to guard against worsening itchiness.

Many people use the natural approach to flea control effectively and, although it is not always as easy as using chemicals, it’s generally safer for your pet and your family. Regarding chemicals, the US Environmental Protection Agency recently completed an in-depth investigation due to the hundreds of reports of illness and death in pets and serious adverse effects were reported for every product EPA assessed. EPA is in the process of increasing restrictions on their use. You can read more information about this report here: http://www2.epa.gov/pets/epa-evaluation-pet-spot-products-analysis-and-plans-reducing-harmful-effects

Besides, most chemicals, including bombs and sprays, kill only adult fleas or adults and larvae. That leaves thousands of tough little eggs and cocoons just waiting for the proper conditions, when they’ll renew their assault once more.

That said, you must keep in mind that a product labeled as “natural” or “organic” could still be not suitable, or even harmful, for your pet. Therefore, I recommend consulting with your veterinarian or trying to find a holistic veterinarian who can offer you guidance about natural flea control products.
