My cat is shedding a lot and has bald spots. What's the cause?

[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.

Hi. It is difficult to say from the photo. Hair loss can be caused by infection, allergies, irritants, yeast, ectopic parasites like mites/fleas/etc., and many more. I would recommend getting him seen by your veterinarian, and having them perform skin testing based on mist probable cause

This fur loss could be due to fleas, mites, allergies, ringworm, or a medical condition like hyperthyroidism. In order to know how to stop it, the cause has to be diagnosed. I'd take Pshy into the vet to get this diagnosed and treated. 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

Miakat is probably suffering from a skin condition that is causing this, it could be an allergy, parasites (mites or fleas), a fungal infection or even an hormonal problem. you should take her to the vet in order to get it checked and treated.

Hair loss can be a sign of external parasites like fleas or mites, allergies to food, or seasonal allergies. In some rare circumstances cats seem to over groom themselves due to anxiety. It sounds like Tota may have a seasonal allergy to something in the environment since her symptoms seem to come and go. There are some prescription medications that can help with allergies so I'd recommend making an appointment with your veterinarian.

Jimmy may have a bacterial or parasitic infection causing hair loss, or allergic skin disease, or some kind of hormone imbalance causing the hair loss. He needs a full workup by a vet to include bloodwork and and skin scraping to look for mites/parasites, and to get him on the right medication to make him feel his best and grow the hair back.
