Why is my cat overgrooming & losing fur? Vet diagnosis & costs.

[Allergies](https://www.petcoach.co/cat/condition/feline-allergies/) are the most common cause of hair loss and [excessive grooming in cats](https://www.petcoach.co/article/excessive-grooming-in-cats-what-it-means-and-how-to-help), but there are several other medical causes as well - including [fleas](https://www.petcoach.co/article/5-tips-to-get-rid-of-fleas/), bacterial or fungal infections, or skin mites. I would definitely start your cat on a good monthly spot-on product such as [Advantage II](https://www.petco.com/shop/en/petcostore/product/cat/cat-flea-and-tick/cat-flea-and-tick-drops/advantage-ii-once-a-month-cat-and-kitten-topical-flea-treatment-over-9-lbs) to make sure fleas are not the problem - you can get this over the counter at many pet stores. If this doesn't resolve the problem, you will need to have your cat examined by a vet - he/she can do some testing if needed to diagnose the problem and get your kitty the appropriate prescription medications to treat it. Behavioral causes, such as stress or anxiety, can also lead to overgrooming. [Calming supplements](https://www.petco.com/shop/en/petcostore/category/cat/cat-training/cat-training-calming-aids/calming-cat-supplements) or [pheromone products](https://www.petco.com/shop/en/petcostore/brand/feliway) can be found at the lcocal Petco. If these do not improve the condition, your veterinarian may recommend prescription strength remedies.

The treatment needed would depend on what is causing the problem. It may be [allergies](https://www.petcoach.co/cat/condition/feline-allergies/), or an infection. A visit to your veterinarian would help identify the most likely cause and point you in the direction of the best treatment. It sounds like her issue is quite severe if she's making herself bleed, so I would get her in to see your veterinarian as soon as you can. If her issue was quite mild, a soothing spray, such as [Zymox](https://www.petco.com/shop/en/petcostore/product/zymox-spray-with-5-hydrocortisone), may be helpful but I'm afraid Phaedra's problem may be beyond conservative home care. Get her in to the veterinarian or a [veterinary dermatologist](https://www.acvd.org/tools/locator/locator.asp?ids=16_Find_Dermatologist) when you can! Thanks for asking PetCoach!

I recommend to either have Lilly checked for hyperthyroidism or try a diet trial with a hydrolyzed protein for 12 weeks. Call your vet to discuss which option seems like the best for Lilly. Unfortunately, Allergies to something in the environment, food allergies, flea allergies and hyperthyroidism will all look the same so you must start ruling them out one by one. You may also look into joining a clinic like Banfield or VCA that offer wellness programs. These programs are not insurance but the office visits are free and you get a discount of services and medications outside of the program. You will need to check and verify details with any of these clinics in your area. Not every service will be covered by the program. I hope this helps and please feel free to post any additional questions.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. What you are seeing on Luna may be insect bites or a skin condition known as eosinophilic granuloma complex. I would recommend having a veterinarian examine Luna so that the most appropriate diagnostic and treatment recommendations can be made. She may need a steroid shot to treat this if it does not resolve on its own. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further. Please take the time to mark this question as helpful or not as it helps us to improve on the quality of our answers to other pet owners. Thank you kindly!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Lilly! I would have Lilly rechecked. At a bare minimum she needs medications (prednisolone taper) to relieve the itching. I would request that a skin scrape be performed to rule out skin mites. They are microscopic and need to be looked at under a microscope. I would also culture the area for ringworm. She may have allergies and I would suggest trying to change her diet first. Chicken is the number one allergic protein so try to change her to all venison or salmon diet. You will need to give the diet 2-3 months to see if it works. If mites, ringworm and food allergies have been rule out then I would consider it behavioral and start her on prozac. I hope this helps and I wish you and Lilly the very best! Happy New Year!

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!

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!
