Why is my senior cat suddenly getting a balding patch on his back?

Risia could be overgrooming, and that can occur due to stress, fleas, mites, allergies, or a medical illness like hyperthyroidism. I'd have her seen by a vet on Monday for a health check and a geriatric blood panel and urinalysis. Once a cause is found, the vet can discuss treatment options. I hope this helps!

That could be one of many things: * trauma/injury * bacterial infection * ringworm * burn Hard to say. I suggest you apply this topical wound gel for about 7-10 days. If no improvement or it gets worse then your vet needs to see it.

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. From the photo there does not appear to be any bald spots, however, it is not a very close up view. Honestly, unless there are bald spots and/or she is scratching the area I would not be too concerned. If the problem persists though (like for a few months) then you should take her to your vet for an exam. Some reasons there could be changes in the hair coat: 1. Diet - the special diet she is eating may be causing some nutrient imbalance. You should talk to your vet about putting her on a supplement for her coat (like fish oils) as this may help. 2. Skin Allergies - even if she has never had any symptoms of allergies before, they can develop over time. If this was the case though, I would expect hair loss and/or scratching, redness of the skin, etc. If you are not seeing any of that then this is not as likely to be the problem. 3. Fleas - again, I would expect hair loss and scratching. If you are not noticing that, then this is also not very likely to be the problem. 4. Stress - even if you don't think your cat is stressed, she could be. Try to see if you could think of anything that could be causing stress like visiting family, stray cats hanging around outside, you got a new pet, new furniture, etc.... 5. Thyroid disease- either a low or high thyroid can cause problems with the hair coat. Your vet can do a blood test to check for this. Hope this helps. Best wishes.

HI, thanks for using Petco Pet Education Center, formerly Petcoach! A lot of times older cats have harder times grooming themselves, whether it be from arthritis, obesity, or underlying medical problems. I think it is important to be sure she isn't suffering from fleas, ringworm, mites or a skin infection. Since she is almost 15 years old I recommend having some blood work done. Be sure she isn't pulling her own hair out which can be a sign of allergies or behavioral issues. I think scheduling an exam with your Vet is the best thing since this is a new medical problem. If all things check out normal then you can try an Omega 3 fish oil supplement to see if that improves her coat. I hope this helps and I wish Lilabit the best!

From the photos, it looks like the skin has some red lesions. Hair loss can indicate many things including over grooming, ringworm (which humans can get), scabies (which can also effect humans) or other skin mites, hyperthyroidism or allergies (fleas, food or environmental). Unfortunately, all these lesions look similar. A physical exam and some basic diagnostics are needed to determine the underlying cause. Over grooming is more difficult to determine and is generally determined based upon ruling out other causes, a physical exam and a thorough medical history. I think your best option is to have Puds examined by the veterinarian. At home you can try giving him an omega 3 fatty acid supplement for pets but it may not correct the underlying cause. This can however improve over all skin health. There are two brands of food, Royal Canin and Nutro, which are aimed at skin health and they may help as well but again, they may not affect the underlying problem. I hope this helps and please feel free to post any additional questions.

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). 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.

[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.
