Why is my new cat losing hair, has scabs, and seems inactive?

The most common problem causing Milly's symptoms is a severe flea allergic dermatitis. Regardless I recommend brushing her to remove the old fur and skin, giving a bath with a hypoallergenic shampoo and using Advantage flea prevention on her. You can purchase it at PetCo. She may need antibiotics to heal the skin and your veterinarian will do an exam to determine the cause of her problems. They may run a blood panel in addition to determine if she is anemic or has a metabolic problem. Once they have a diagnosis they will give her the appropriate treatment and hopefully she will recover quickly. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Milly.

Hair loss in a young kitten is most often due to parasites including fleas, mites and lice. If Maple is not already on a topical flea preventative, I would recommend getting one immediately. Keep in mind that fleas will remain in the environment so you will need to clean/disinfect Maple's bedding as well as any furniture she lies on, blankets etc. If this does not improve the situation, I recommend you take Maple to the veterinarian to check for mites, fungal infections or diseases including allergies.

It looks like your cat has a skin infection, most likely caused by allergies or fleas. The allergies can be from a protein in her food or to something in the environment, like grasses, pollens, dust etc. I would recommend taking your cat in to see the vet so she can be started on some antibiotics to help clear up her skin. I would also recommend discussing with your vet some options for medication to help control her allergies and itch like Atopica.

[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.

This is probably due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment (advocate or advantage), then ask 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 to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics). Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Oreo. Skin and hair coat problems can be caused by a variety of things including external parasites (fleas, ticks, mites, etc), nutritional problems including loss of nutrition/blood by intestinal parasites, other dietary issues, bacterial/fungal infections, among many others. I don't think the food is causing a problem unless you are not feeding kitten food and I have never heard of the litter causing a problem like this unless it is getting caked onto the hair and skin. They are definitely old enough to be dewormed and I would highly advise that. Deworming should start at 2 weeks of age and be done every 3 weeks for at least 3-4 times. If these areas of concern worsen and persist, I would highly advise you have your vet evaluate Oreo to try to figure out what is going on. It doesn't seem like it's something contagious but sometimes not all kittens are affected. Your vet can advise some tests if needed (skin scrape, skin cytology, fungal culture, woods lamp exam, etc) to try to determine what is going on. Once a diagnosis is made or suspected, a sound treatment plan can be put into action. Your vet can also advise you on a sound preventive health care plan including deworming, testing, vaccines, flea/tick control, etc. Good luck with Oreo.

While it is hard to say exactly what the cause of Bella's hair loss may be due to without examining Bella first, I can offer some possibilities and next steps. Some possibilities may include a fungal infection, bacterial infection, mites, a food or environmental allergy, or evidence of an underlying endocrine disorder such as a thyroid problem. Your veterinarian can diagnose these potential conditions with a fungal culture, skin scraping, and some blood work. I would recommend Bella visit her vet soon to have the possibilities above ruled out so she can get the most appropriate treatment.
