How to Identify Common Pet Problems ?

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

There are many suspected causes of pruritus, including fleas, scabies, lice, allergies, bacterial infections, abnormal cell development (tumors), immune disorders, and allergies. Diseases of the endocrine are thought to cause pruritus in nearly 30 percent of the affected ferrets.
Skin irritation and pruritus is fairly common in all animals, including ferrets, and is usually not a cause for concern. Some of the most common symptoms of skin irritation that your ferret may exhibit include: Scratching.
Eradicating fleas can be difficult. Currently, the best course of action is bathing the ferret with a flea shampoo. These baths should be done once a week for up to several months, or until there is no sign of adult fleas on your ferret.
A ferret may bite because of pain, but they may also bite to get attention. When you are busy and the ferret wants to play, it is common for them to nip your foot or ankle to say “Hey! I`m down here and I want something.” Realistically, that`s the one part of you these short little animals can reach.
Scruffing is one of the most popular ways to stop your ferret from biting. Grab your ferret by the loose skin on the back of the neck, and lift it to your eye level. Close the mouth with your index finger and thumb. Look at the ferret and say, “No!” in a loud and firm voice.
As you mentioned, skin parasites (also termed ectoparasites) can cause disturbances on the skin leading to increased biting and scratching. You report no fleas, but some mites and lice can cause these issues in ferrets, and finding these very tiny ectoparasites is very difficult without a microscope.
Your ferret is in a “fight or flight” mode. Your ferret may also hiss while doing this to vocalize that it is upset. Hissing also can be just an indication that your ferret doesn`t like something; this means that hissing by itself is not necessarily an indicator of fear.
Citronella, eucalyptus, peppermint, tea tree, and rosemary will all naturally repel fleas. If your dog doesn`t mind a spray bottle, dilute a few drops of your chosen essential oil into a 300ml-400ml of water and spray directly onto your dog`s coat.
Vinegar water is a cheap, easy to make, effective, and safe around ferrets! Mix half white vinegar and half water into a spray bottle.
Wash your hands thoroughly with soap and water after handling ferrets or their food, cages, or bedding. Hand washing will reduce the risk of germs spreading from your ferret to you and your family. Avoid bites and scratches from ferrets by learning how to approach and hold your pet safely.
You can never go wrong with a nice belly scratch! Ferrets are suckers for long, affectionate belly and back rubs, and they`ll show you how much they love it by licking and nibbling on your hands while you rub and pet them down.
Fear: If you startle your ferret or do something that causes it to be scared, biting is likely to occur. Playing: Ferrets often use their mouths to chew and play bite so this can be a normal behavior.
Ferrets like to play games; two of their favorites are tug of war and hide and seek. They also love to swipe and hide things, so keep your wallet, keys, etc. in a location that is inaccessible. They enjoy almost any cat or dog toy, especially round toys such as balls.
As the ferret ages (4 years and up), expect the ferret to remain alert, interactive and playful. But his energy and playfulness decreases with age. As a kit, a ferret might play for hours, but do not be surprised if your 5- or 6-year-old ferret doesn`t have the energy to play for hours.

There are many reasons why pets become itchy. Sometimes the cause can be fleas, even if you can`t see them on your pet. Some pets experience seasonal allergies, just like people, but instead of having a runny nose and other symptoms we associate with hay fever, they actually get itchy skin.
The fleas can cause itchy welts on exposed skin for several weeks or even months. A severe allergic reaction may even lead to secondary infections. If a flea bite is not treated right away, the reaction can become persistent.
The first thing to realize is that it is a MYTH that all dogs and cats with fleas are itchy! They are only very itchy if they have an allergy to the flea`s saliva (flea allergy dermatitis). We see animals in frequently in the spring and fall for their physical exams and we find fleas randomly on their exams!
Giving kisses is the ultimate sign of a ferret`s affection. If your ferret loves you, he will kiss you on the arm, face (especially nose and eyebrows), feet, and any other part of the body.
Ferrets can also get very ill or die from an overdose of salt. Don`t give your ferret chips or other salty snacks. Do give your ferret specific edible chew toys and different brands of ferret or kitten food as a treat.
Ferrets really enjoy spending time with their human companions are usually happy to be picked up and cuddled. If they`re frightened or accidentally hurt, ferrets can give a strong bite. Getting them used to being picked up when they`re young is really important.
Wash all bedding in hot, soapy water

For mild infestations, wash your bed sheets in hot soapy water. The soap will kill fleas, while also destroying their eggs and larvae. Consider vacuuming your mattress as well. Don`t forget to do the same to your pet`s bed.

Natural flea repellents such as citronella, eucalyptus, peppermint, and geraniol may naturally repel fleas. If your pet doesn`t mind a spray bottle, dilute a few drops of your chosen repellent into 10-13 fl oz of water and spray directly onto your pet`s coat.
After tending to the fleas on your pet, it`s time to get rid of the infestation in your home. In most cases, it takes three to four months to completely get rid of a flea infestation since it takes fleas this long to go through their life stages, according to the American Kennel Club.

the most relevant questions and answers related to your specific issue

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.
