How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

When you can`t live without your pet, a medicine for dog and cat allergies can help control your pet allergy symptoms. ZYRTEC® starts working at hour 1 and stays strong day after day, so you can reduce your cat and dog allergy symptoms.
Pet-friendly antihistamines, such as Chlorpheniramine, are anti-allergy medications prescribed to pets with frequent allergy symptoms. These treatments aren`t always effective, and it can take up to 10 days before you notice them helping your cat.
All ZYRTEC® medicines start working at hour 1 on the first day you take it. Can I chew or swallow the dissolve tabs?
Some of the best antihistamines for cat allergies include Curist Allergy Relief (levocetirizine), fexofenadine (brand Allegra), and cetirizine (brand Zyrtec). These oral antihistamines are effective at reducing cat allergy symptoms such as sneezing,and itching.
Dosing Information of Cetirizine for Dogs and Cats

Medication should never be administered without first consulting your veterinarian. Cetirizine is dosed in dogs at 0.5 mg per pound (1 mg/kg) orally once to twice daily. In cats, cetirizine is dosed at a total dose of 5 mg per cat once daily.

At high doses, sleepiness has been reported in small dogs and cats. Any side effects that are severe or worsen should be reported to your veterinarian. This short-acting medication should stop working within 24 hours, although effects can be longer in pets with liver or kidney disease.
Build up resistance. There is no cure for allergy to cats (yet!), but immunotherapy may help increase your tolerance. Immunotherapy involves getting allergy shots once or twice weekly for up to six months, then monthly boosters for three to five years.
Antihistamines (Zyrtec, Claritin, Allegra, Benadryl)

They fully kick in within a few hours. Nasal spray antihistamines can start working in as little as 15 minutes.

Most people experience at least 24 hours of relief after a single dose. Zyrtec, on the other hand, is fast acting. People who take it may feel relief in as little as one hour.
The dermatologists on VIN (the Veterinary Information Network) seem to agree: Good, safe stuff for cats, this Zyrtec. Probably more effective than the alternatives. And definitely easier because, for cats, we now know that once-a day dosing is perfectly appropriate.
Cats should be given somewhere between 2.5 – 5 mg of Cetirizine, never exceeding the 5 mg cap. These dosages are only an educated estimate and a licensed vet should be consulted before starting any new drug regimen. In some cases, vomiting or hypersalivation has occurred after starting on Cetirizine.
For Cats: Allergy Meds

Pet parents can give their cat Zyrtec (cetirizine) – 5mg (1/2 tablet) once daily (one full tablet of adult Zyrtec is 10mg).

The typical Zyrtec dosage for people ages 6 to 64 years old is 5 mg to 10 mg once daily, depending on the severity of allergies. For children 2 to 5 years old, the typical dosage is 2.5 mg to 5 mg a day. For adults ages 65 and older, the recommended Zyrtec dosage is 5 mg once daily.
Side effects for cats taking Zyrtec are usually mild. Some of the most common are vomiting and feeling drowsy. As always, if you notice any sort of allergic reaction when administering this medication to your cat, make sure to contact your veterinarian immediately.
Take Allergy Medications at Night

Many allergy medications, such as Zyrtec, are recommended every 24 hours. By taking the medication before bedtime you`re more likely to get through the night without the active ingredients wearing off or becoming less effective closer to the end of the 24 hour period.

Nasal sprays, antihistamines and bronchodilators can help relieve symptoms. Consider allergy shots ( immunotherapy ).
While there is no “cure” that will make you immune to cat allergens, there are several actions you can take to significantly reduce cat allergens in your home and alleviate your symptoms.
For example, a person with a mild allergy to cats or dogs may do well with Claritin. Another person with more severe allergies may do better with Zyrtec. However, Dr. Qamar says that although Zyrtec may be more effective in some patients, “around 10% of people can become sleepy with it.”
Some people are lucky enough that they eventually develop an immunity to cat allergies. While this is certainly possible, allergic reactions may also worsen with more exposure. It`s also possible that someone who has never suffered an allergy to cats before can develop one.
Outgrowing allergies to animals is possible but not probable. Also, even those allergies can go away; they can come back again later in life. Keeping pets will not help to acclimate to allergies either. For some people, allergy symptoms can be worse in some seasons, especially in the heat when animals shed more.
Most often, pet allergy is triggered by exposure to the dead flakes of skin (dander) a pet sheds. Any animal with fur can be a source of pet allergy, but pet allergies are most commonly associated with cats and dogs.
Official answer. Cetirizine can be taken at any time of the day. In most people it is non-sedating, so they take it in the morning. However, a percentage of people do find it to be sedating so if it does make you drowsy it is best to take it in the evening.
Absorption: Cetirizine was rapidly absorbed with a time to maximum concentration (Tmax) of approximately 1 hour following oral administration of tablets or syrup in adults. Comparable bioavailability was found between the tablet and syrup dosage forms.
ZYRTEC® Allergy Relief Tablets

Adults under 65 and children 6 years and older One 10 mg tablet once daily; do not take more than one 10 mg tablet in 24 hours. A 5 mg product may be appropriate for less severe symptoms.

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. 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. I have a cat with that virur (aids) could u tell me about her disposition and care
ANSWER : A. Thanks for your question.

Unfortunately the discussion about what you asked has no straightforward answers and can be quite complex.

First thing that I would double check, considering that your cat is very young, is whether she is really infected. It is important to remember that kittens born to FIV-infected queens will receive antibodies from the queen via the milk, and so will test positive early in life though they may not be infected. Kittens with a positive test result should always be retested when they are 5-6 months of age.

Many FIV infected cats are able to live happily with the virus for a long period of time, and indeed the virus will not necessarily ever cause clinical disease.

Different factors will influence the onset of disease in your cat including:

– The ”subtype” of FIV your cat is infected with,

– Her immune response

– The presence or absence of other infectious agents.

To maintain a good quality of life for your cat, I will give you these general guidelines, but you will then find certainly helpful to speak with your veterinarian for specific cases.

– Some antiviral medications used in human patients with HIV infection have also been shown to help some cats with FIV infection. Interferons may have anti-viral effects and modify immune responses. A recombinant feline interferon (feline interferon omega) is available in some countries. Down side is the cost usually.

– Keep your cat away from other cats and possible source of infections;

– Maintain good quality nutrition;

– Keep your cat indoor if possible regularly checked by your veterinarian;

– Keep your cat away from non-infected cats.

Q. Cat was vomiting for a few days. Took to vet, received anti-nausea medicine 2 days ago. Drinks and no longer vomits, but won’t eat. I’m worried
ANSWER : A. If your cat has been feeling nauseated, it is possible that the nausea, or just general illness is making him want to eat less. However, you can try enticing him to eat with a few tricks geared to cats.

Warming up wet foods or even bland people foods such as plain chicken or boiled hamburger can make food more interesting to cats. Cats tend to go for aromatic rather than flavorful foods, so making the food as “smelly” as possible may encourage your cat to take a bite. Bland foods are also good for helping to soothe upset stomachs, which may still be happening if your cat had recently had a vomiting episode.

However, if enticing your cat to eat does not work, or he continues to refuse to eat any food, it is best to contact your local veterinarian for more care and testing. Cats can become very ill if they refuse to eat for more than a few days, and finding the underlying cause can help your cat feel better.

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. How should I interpret my cat’s tail movements?
ANSWER : A. Our feline friends express themselves in many different ways, including through the use of their tails. Most pet owners pay close attention to a happy or excited dog, but they are sometimes less attentive to the posture and movement of their cat. Here are some of the most common cat tail behaviors, and the underlying emotion behind each action:

A flicking tail: Many anxious, nervous or stressed cats will hold their tail in a low position and flick it quickly back and forth. This is often referred to as angry tail, and a pet owner or veterinarian should be on guard for any possible aggressive or defensive activity. If a cat is moving their tail slowly, and not exhibiting the flicking motion, then this cat is at a much calmer state.

Vertical position: Most of the time when a cat is holding their tail in a straight, vertical position this is indicating curiosity and a playful mood. A cat chasing after a laser pointer or playing toys will often have their tails in a vertical position showing their enjoyment. This position also helps with balanced movements. In contrast, if the tail is in the vertical position and the cat’s back is arched with pinned back ears then this could demonstrate a feeling of being threatened and thus result in defensive or aggressive behaviors.

The Tucked Tail: Similar to a dog, a tucked tail often indicates submission or fear. Your cat is conveying upset feelings and should most likely be left alone. This tucked tail appearance can also make a cat look smaller and less threatening to an aggressive cat.

The Tail Twine: Cats will often hook their tail around another cat’s tail, owner’s legs or other objects to show a friendly and affectionate nature. They are also trying to indicate whether they want to receive affection from their owners, be fed or have playtime.

The next time you are home with your feline companion take note on how they express themselves through their tail movements, their ears, body posture and vocalization. You can start to better understand their needs and wants, in addition to what makes them uncomfortable or happy. Cats will surprise you with their array of emotions and varied expressions they can express.

Q. My cat will not eat the renal food my veterinarian recommended, can I feed a grocery store food?
ANSWER : A. Your veterinarian recommended a therapeutic kidney diet because it has ingredients that will help slow the progression of your cat’s conditions, especially phosphorus and lower protein levels. Many of the non-prescription or grocery store foods generally have high levels of phosphorus and would not be ideal for your cat.

To help your cat accept the new food It is important to do a transition. There are two reasons to do a transition:

1) Occasionally a pet will have a GI upset when switched to a new diet,

2) A pet will accept a new food better when a transition is done to allow the pet to get use to the new texture and flavor.

There is more of a chance with a hydrolyzed protein or different (high or low) fiber level food to cause a GI upset. Transition recommendation:

1) Recommend ¾ old diet – ¼ new diet

2) Do this for a few days; if no GI upset, go to the next step

3) ½ old diet – ½ new diet

4) Do this for a few days; if no GI upset, go to the next step

5) ¼ old diet – ¾ new diet

6) Do this for a few days; if no GI upset, go to the next step

7) End with 100% of the new food.

Sometimes a transition should be longer, especially for cats. Use the same recommendation, but instead of a few days, recommend doing each step for a week or more. If you cat is still not interested in the new diet you can research other non-prescription diets focusing on the labels for appropriate levels of phosphorus and protein.

Also, home cooking may be an option but make sure to provide adequate nutrients. A good website to consult is balanceit.com. This website helps you to create well balanced home cooked recipes and offers supplements to add into the diet.

Q. My cat is pooping outside of the litter bix. He is 2 1/2. He did this as a kitten. It stopped then started about 3 months ago. Litterbox is clean.
ANSWER : A. Inappropriate elimination or house soiling can be a frustrating problem but with a bit of detective work on your part, there is hope. First, before deciding that this is a behavioral issue, any medical problems (diarrhea, constipation, fecal incontinence, pain on defecation, etc.) need to be ruled out and/or treated. If your cat receives a clean bill of health from your vet but is still eliminating outside the litterbox, then we need to consider that something about the box itself might be aversive to your cat. Cats can be quite finicky about their litterbox and toileting habits. Below I have listed common recommendations and cat preferences for litterbox use. Review the list and make any changes that could account for your cat’s aversion to defecating in the litterbox:
* Soft, fine-grained clumping litter (vs, coarse-grained, non-clumping litter)
* Unscented
* 1 – 1 1/2 inch depth (especially older cats or cats with hip problems)
* Larger pans (especially for large cats) – want to get whole body inside – poop just outside the box might mean the box is too small
* Open, non-hooded
* At least one shallow side to get in and out easily
* Easy to get to – not hidden away, preferably in areas they spend time in or near – and not near appliances that make scary, unpredictable noises (washers, dryers, refrigerators)
* Scoop minimum 1X/day – preferably 2
* Clean the litterbox with soap and water and put in fresh scoopable litter at least once/month (instead of just continuously adding)
* Some cats prefer to urinate in one box and defecate in a separate box, so you may need 2 boxes even if you just have 1 cat. Multi-cat households should have 1 box/cat plus 1 extra.
