My cat's losing fur after diet change. Is it allergy or anxiety?

Hi, and thanks for your question. This could be due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment, then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. Please find the time to give us a feedback about the consultation as that will be used to improve our service.

If there is no medical reason such as fleas or food allergy and it is behavioral there is medication to help. She may notice another animal or cat outside that is new that is stressing her out and causing her to do this more, There may be a new neighbor with a dog that she smells passing by the door increasing her anxiety. You can start with feliway diffusers and sprays to help in side the apartment. You can also talk to your vet about anxiety medication to start her on to decrease this behavior.

I would be very suspicious about possible allergies with these symptoms. I recommend rechecking with your vet, as that skin on the legs looks pretty raw and you need to make sure Cindy doesn't have a secondary infection. Then you can talk to your vet about whether they think it's appropriate to start Cindy on an allergy medication / food trial. Anxiety / behavioral overgrooming and parasites (fleas, mites) are other common causes of hair loss, and with an exam your vet can help differentiate these.

Aw, what a handsome boy! I’m sorry the treatment didn’t give him relief. You can try a product, such as [Zymox](https://www.petco.com/shop/en/petcostore/product/zymox-spray-with-5-hydrocortisone), on the areas where he seems most bothered. Also, I would recommend a “no additive” cat litter such as [Yesterday’s News]() or [Feline Pine](https://www.petco.com/shop/en/petcostore/product/feline-pine-cat-litter). It may be that his anxiety is contributing to his [over grooming](https://www.petcoach.co/article/excessive-grooming-in-cats-what-it-means-and-how-to-help), so you might ask your vet about trying him on a medication such as [fluoxetine](https://www.petcoach.co/pet-medication/fluoxetine/). If none of this helps, it may be best to consider a consultation with a [veterinary dermatologist](https://www.acvd.org/tools/locator/locator.asp?ids=16_Find_Dermatologist) to get as directly to a diagnosis and proper treatment as possible. Thanks for asking PetCoach!

Such overgrooming in cats can be related to allergies or anxiety - feeding a calming food such as royal canin calm or adding a claming supplement containing b vitamins, tryptophan and casein can also help. Occasionally antiinflammatory medications may need to be prescribed by your vet in order to break the recurrent itch-scratch/groom cycle and allow the skin to heal

Hello, and thank you for your question. Fur pulling can be a behavioural response to stress, or it could be due to a medical problem such as itching from bacterial infection, ringworm, mites or fleas, or allergies. Contact with a male human is unlikely to be the cause. More common causes of stress would include any new human (male or female), new pets, change in environment, stressful noises, or stress due to pain. I would start by eliminating any potential stressors, if present. You can also try using a feline pheromone spray called Feliway, which can help to reduce stress in cats. If this does not help, I would recommend getting him seen by the vet. They can perform some skin tests such as a skin scraping, cytology, or fungal culture, to rule out a medical problem, and prescribe appropriate medical treatments if so. I hope this helps, and that your kitty feels better soon!

It could be due to food allergy but it is more likely to be due to fleas. treat her for fleas first with a high quality spot on such as Advantage and see if it solves the problem. if not try to switch her back to her previous food.
