Why is my cat excessively licking and losing fur despite vet visits?

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.

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.

Your kitty is likely a nervous or stressed cat, especially if stressful events (new neighborhood cat, new boyfriend, new baby, mvoing, removing or adding furniture, new puppy , etc.) have happened before she started the excessive licking. This licking pattern would be typical for overgrooming. Your vet needs to rule out parasites, fungal and bacterial infections. If there is none of these then you can try to help your cat by removing anything stressful in the house that can be removed and placing Feliway dispensers in the areas she spends most of the time. Feliway is a pheromone that makes cats happy and takes away stress. You will need to do this for at least two months before you will see success. If this does not work, then your vet can do some medication trials to see whether she will stop the overgrooming.

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

Hello! Cats can start this behavior which we call barbering or over grooming. To my knowledge there is no specific known cause but it has been linked to stress and allergies. Since this is thought to be more of a behavioral issue the options for treatment are centered around environmental enrichment and/or behavior modifying medications. I would recommend discussing this further with your regular veterinarian so they can also evaluate Tess' to rule out things like a primary dermatological problem. Some have discussed switching to a hypoallergenic food to see if that helps. I have also met many owners who choose not to do anything because like Tess they aren't causing trauma to themselves. Hopefully this information is helpful and best of luck to you and Tess.

Overgrooming can be caused by a few medical problems, such as fleas, food allergies, mites, or internal medical disease. I would take Milly to a vet to rule out these issues. If the vet can't find anything physically wrong, then it could be behavioral. You can try supplements for stress like Zylkene or Comfort Zone/Feliway.
