My cat has a bald spot after cattery. Is it overgrooming or illness?

You need to diagnose the cause of this behavior in order to treat Pumpkin successfully. It could be stress, fleas, mites, allergies, ringworm, or a medical condition such as hyperthyroidism causing the over-grooming. I'd take her into a vet today for a health check. Best of luck.

It may be excessive grooming, which can be caused by numerous things, including fleas (even if she is an indoor-only cat), stress or anxiety, skin infection, mites, pain, or even urinary discomfort. I would recommend having Izzy checked out by a vet to first rule out common medical issues. Then they can help you determine what could be the cause and start her on an appropriate treatment plan. https://www.petcoach.co/article/excessive-grooming-in-cats-what-it-means-and-how-to-help/ https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4952646

[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.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Moochie. This hair loss could be due to over-grooming. This could be caused by stress but in a cat her age it could be caused by a medical condition such as hyperthyroidism. I'd have her seen by a vet to get this checked out, and I recommend getting a geriatric blood panel and urinalysis done. I hope this helps!

Thanks for using Petco Pet Education Center, formerly Petcoach! Without seeing Mathilda it is hard to say what is going on. It sounds like it she has an allergic reaction to something. This could be a pollen, dust, fleas, food- anything she could be exposed to. I recommend taking her to a vet so they can see the area and make sure its not a skin infection, too. She may need a antibiotic, too. Good luck and kisses to Mathilda!

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.

Two things you didn't mention: Was Mikimoto-san tested at all for thyroid issues or other metabolic issues? Sometimes thyroid and other issues can present with changes in weight, eating habits, hair loss and more. A full blood panel if you haven't had one done already can help. The other thing to look for is stress over-grooming. Cats can start obsessively licking as a result of stress, and the behavior can become a habit that continues even after the stressor is removed. Making sure Miki-san has his own place to relax, eat, drink, use litter and more can help reduce stress as well as using pheromone diffusing plug-ins or collars. If the stress has been removed but the licking continues, you may need to break the habit by placing an Elizabethan (cone) collar or T-shirt on him to prevent licking until he doesn't feel the urge to continue.
