Why is my cat with kidney disease losing hair in clumps, not itchy?

Hair loss and overgrooming can be a sign of external parasites like fleas, a food allergy (although this is less likely at Greta's age), or an environmental allergy. Some cats can also overgroom as a reaction to pain or due to anxiety. I would recommend having Greta examined by your veterinarian to rule out fleas and discuss a potential allergy work up. I would not recommend changing her food until you talk to your vet - diet is the cornerstone of managing chronic kidney disease, and there are hypoallergenic kidney diets available if your veterinarian thinks Greta may have a food allergy.

I really do not know what that is from. If he has been over-grooming or scratching a lot I would be worried about fleas. If he has no other symptoms you can try this wound spray gel on that area to see if it helps. I do see some red bumps in that hairless area. If no improvement after a few weeks then you should have him to the vet for an exam. It should have nothing to do with renal disease or diet.

This is probably due to an allergy, although it could also be infection or mites or it could be stress related. 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). If allergy is not identified this behaviour could be purely stress related. Some medications can be given by the vet in order to repair the skin lesions (steroids and antibiotics).

[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.

Skin problems are not normally associated with CKD in cats, so it's likely that this is an unrelated problem. She may have skin allergies, a bacterial or fungal skin infection, or even an ear infection causing scratching in this area. If the scabs don't resolve on their own in the next few days, it would be a good idea to have her examined be a vet to determine what is causing them.

I am Sorry to hear that Neo is exerpwicing these issues with his fur. It sounds like he is a happy and healthy cat otherwise! A few different things could be happening that I would be advise investigating. It could be possible that Neo has seasonal or environmental allergies. This might mean he would benefit from regular medication which could be prescribed from your veterinarian. As you were only there 5 months ago they may be happy to write you a prescription without a visit to the clinic. It is also possible that there is an underlying medical condition. Such as kidney disease or hyperthyroidism. I would advise ruling out the simple first and trying to treat for allergies. If after a few weeks his hair hasn't started to come back in with the medication, then perhaps try investigating further causes with a blood test and potentially a skin scrape. Best of luck with your lovely Neo.
