There are a number of different causes of this happening in Gracie. This could be a hypersensitive reaction to food, skin parasites (fleas), infections (bacterial, fungal, or stress). It could also be caused by hyperthyroidism. If Gracie isn't up to date on her flea treatments, I would recommend giving her a spot on treatment such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash her bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. If she is up to date on her flea treatments, then I would take her into the vet for an exam. The vet can do a physical exam, routine blood tests, and a urinalysis to determine what is causing her to have symmetrical hair loss on her belly. Once the cause is found, the vet can institute the appropriate treatment.

My cat is losing hair on her lower belly. Is it serious or treatable?

Hello. There can be a couple of reasons for the hair loss. One could be from allergies, or this could be a type of psychogenic hair pulling, a behavioral problem. For the most part, this is not dangerous, but you do want your vet to evaluate Cleopatra. If it is an allergic reaction, it can be easily treated. If it is psychological, you do want to work through the reasons she has begun pulling out her hair. Thanks for using Petco Pet Education Center, formerly Petcoach.

My indoor cat is losing fur on her belly, but seems healthy. Why?

Hi there. A couple things could be going on with Lucky. Some cats lose hair due to stress and this is usually self resolving. More commonly cats lose hair due to an allergy. This could be to their food or something in the environment. I would start by having your vet check her and then do a hypoallergenic food trial for 8 weeks. This usually does the trick, but if not your vet can prescribe medications to help with environmental allergies. Best wishes to you and Lucky.

Why is my cat losing hair on her belly and sides? Is it normal?

The hair on the belly which is missing can be a normal finding in a small number of cats, but the hair loss on the side of the body seen in the picture is never normal. Typically the first thing a vet will want to know with any situation involving hair loss is if it is occurring with or without itchiness. If there has been itchiness, the cause of the ailment is most likely allergic, inflammatory, parasitic, infectious, or auto immune in nature. If there is not an itchy component, the cause may be hormonal, psychologist, or also potentially, inflammatory in nature. If Pipi appears to be uncomfortable or is mutilating herself in any way, I would encourage you to have her examined at the next available appointment time. Provided she is still comfortable and not hurting herself, simply continue to monitor for any changes or worsening condition, and make a regular appointment to be seen at the next convenient time. Hope this helps.

What's causing my cat's bald, weepy patches on her belly skin?

This is probably caused by an allergic reaction. first of all make sure you de-flea Lily regularly every month with a high quality spot on (ex. Advantage) as fleas are by far the most common reason for these reactions. If the fleas are not the problem, it could be an allergic reaction to food or an environmental factor. this is more complicated to treat and will sometimes require medications such as Steroids, anti histamines or cyclosporin in order to stop the allergy.

Why is my 15-year-old cat losing hair on her legs, tail, and stomach?

Hello. Decreased hair quality in cats, especially of her age, could be due to hyperthyroidism, kidney disease, diabetes, liver disease, parasites, and overall poor health and grooming habits due to arthritis or obesity. I would suggest getting her checked by a vet, and having bloodwork done to test for these conditions as some have easy fixes. Good luck with her!

My cat has belly hair loss and trouble peeing. What should I do?

I'm quite concerned that Siriano is having trouble peeing, and that she will squat with not much coming out. She could have a severe bladder infection or bladder stones causing her problems. This is a medical emergency when a cat has trouble peeing, and Siriano has to see a vet immediately. The vet can diagnose what is causing her trouble peeing, and can treat her for it. While there, the vet can check out the hair loss on her stomach. You are correct that it could be caused by mange, but it could also be caused by fleas, allergies, or ringworm. The vet can diagnose the cause, and can discuss treatment options with you.

Why is my cat's belly hair thinning and losing hair on her tail?

Without a photo, its hard to say whats happening with Ruby. If the skin looks totally normal (no redness, flakey skin, scabs...etc) then its possible Ruby is simply over grooming. Some cats with lick their fur until it thins out as a habit (like people biting their nails). Hairloss in general can indicate many things: parasites, fungal infections, thyroid conditions, metabolic imbalances. When in doubt, I recommend a trip to the vet to have her thoroughly checked out. Hope you get it figured out soon!
