Why is my cat going bald on her back and belly from over-grooming?

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.

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.

[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.

Wow - Bits certainly has groomed all of the fur off of her abdomen! The two most common causes of overgrooming in cats include allergies and anxiety/stress. I'm glad to hear that all of her diagnostic tests have been normal, but unfortunately, neither of these issues show up with blood tests or imaging. I would ask your vet if they feel that she would be a good candidate for a medication to help manage some allergies in cats (Atopica) or anti-anxiety medication (Prozac is the most common option). The only way to get her fur to grow back is to treat the underlying issue, although it will still take some time and patience. I hope that everything goes well for Bits!

This is probably due to an allergy, although it could also be a fungal infection, fleas or mites. First of all, in order to rule out skin parasites, you will need to treat Pixie with a high quality flea treatment (e.g. advantage), then get her to 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 discovering the cause of the allergy. Some medications can be given by the vet in order to repair the skin lesions (steroids and antibiotics). simultaneously you should start her on a prescription hypoallergenic diet for at least 2 months. Hopefully you will see some results after all this, if not you and your vet should consider putting her on a long term allergy treatment (Atopica).

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

Good job on using a flea treatment program on Ivy, but the environment has to be disinfected as well to prevent continue infestation with fleas. Wash her bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. Cats can suffer from an allergy from the flea bites, and that can cause the continued grooming. If after disinfecting the home Ivy is still grooming, I would have her seen by a vet. Should she be suffering from a flea allergy, the vet can give her medication for it. Other causes of over-grooming in cats include mites and ringworm. The vet can check her for those as well, and treat as needed.
