My cat starting losing hair on her leg about a ...

Resolved Question:

My cat starting losing hair on her leg about a month ago. It stayed small for a while , but over the past 2 weeks has escalated into large and small patches all over her body and some of them have ade her dkin red as others have the hair growing back. There hasn''tbeen a noticable changein her diet and no diharrea so far. We did move about 5 months ago. I also have another cat with long hair, but it hasn''t shown any of these symptoms so far si its just my short haired calico. Do you have any idea what this is or what I can do to help her?

I am so sorry to hear your kitty is loosing fur! Just a few questions to aid us in answering your question. Is your cat on flea prevention? If yes, what type? Has your cat only eaten the food she is currently eating? Is she actively grooming the areas often? Is she scratching her skin? Is she indoor only, outdoor, or indoor/outdoor kitty?
Customer: replied 8 years ago.
Both of my cats are completely declawed and strictly indoor only. I do not currently have them on any flea treatment. She has been eating the same food for years. She has been grooming these areas more often now but not constantly, She originally didn't seem to notice when it first strated until it got so much worse. As far as scratching her skin, I haven't seen her try to scratch yet. I want to take her to the vet, but their fees have nearly tripled over the past few years and things are tight at the moment. I really appreciate whatever advice you can give me.

I am sorry, I should have also asked this question. I know you stated the fur lose was all over, but where on her body is she loosing most of her fur? Or is it about even all over?
Customer: replied 8 years ago.
The largest area of fur loss is on her left inner rear thigh, moving onto her stomach. The small pathces are on her legs and paws. It started on the outside of her left rear thigh which is where the fur is starting to grow back.

There are a few things that cause hair loss on cat. I will discuss a few possible reasons for hair loss. First, it could be a flea allergy. In flea allergy, you cat has developed an allergic reaction to fleas. This causes over grooming. The best way to treat this is prevention. Prevent your cat from being exposed to fleas. Some cats develop infections or need a steroid injection to relieve the allergic reaction. I do recommend a vet visit for this condition to ensure your cat does not have a skin infection. Until then, applying a flea control such a frontline or advantage will help prevent flea from continuously infecting her.

Another possibility is hair loss to an allergy that your cat inhaled, such as pollen, or to her food. Generally, we start to see allergies develop in cats around 3-5 years old. Because you did move to a new area 5 months ago, it is possible that your cat is now being exposed to an allergen that she was not exposed to at the old location. Once again, cats can develop skin infections from over grooming due to allergies, so she should see the vet to ensure she does not have a skin infection.

Another possibility is a fungal infection called ringworm. Hair loss usually occurs in circular patterns around infected sites. Often, you will notice hair regrowth in old infected sites as the infection moves. It is happens to be ringworm, it will need to be treated by a vet. Be aware, ringworm is zoonotic meaning it can be transmitted to humans. If you start to notice circular lesions on you or other household members, seek doctor care.

Less common in cats are mites called demodex mange. These are mites that are common on dogs. The infect the hair follicles, causing hair to fall out. A skin scrapping by a veterinarian will determine if it is mites that are causing hair loss.

Another less common possibility is hyperthyroidism. Hyperthryoidism is when a cat's thyroid gland produces too much thyroid hormones. However, only 5% of hyperthyroidism cats develop symptoms before the age of 8. In addition there are other signs that are more common then hair loss in hyperthyroidism cats, such as weight loss. However, your veterinarian should inspect your cat for this possibility.

There are also many other less common medical reasons for hair loss. Here is a website which provides a nice list and detailed descriptions about possible medical reasons for hair loss in cats: Causes of Hair Loss in Cats.

There is also another possibility. Sometimes, cats can start grooming due to a stress related change such as moving 5 months ago. This grooming behavior is a type of displacement behavior called feline psychogenic alopecia. To combat this problem, there are few things that need to be done. First is to see your veterinarian to ensure that it is not a medical reason for hair loss. Second, increase environmental stimulation, such as kitty toys. But you need to rotate these toy (So that they continue to provide stimulation). You should also engage in play periods or short training sessions (10-15 minutes daily) to help keep your cat focused. You will need to learn not to reinforce the bad behavior (the excessive grooming), and reinforce the good behavior (playing, cuddling, etc.). Two best forms of reinforcement are food and attention. In addition to this all, you should provide a hiding place, where he can retreat to if he needs. Third, speak with your veterinarian about using anti-anxiety drugs to help control this behavior. Patience is needed. Sometimes, these behavioral problems can take weeks to months to correct depending on how much the behavior is ingrained in you cats personality.

I also understand that veterinarian bills have increased in the past few years. I have listed below are several organizations that provide assistance in paying vet bills to qualifying people:

American Animal Hospital Association

Angels 4 Animals

Care Credit

God's Creatures Ministry



The Pet Fund

United Animal Nations

  • My oldest male cat had a seizure this evening. This site was the first place I could think of to go after the seizure had passed. Dr. Lucy was fantastic and she was spot on! Debbie USA
  • I must tell you I found this site by accident and was amazed when I asked a question of the Veteranians online. I wish I could have found it sooner it could have made such a difference in the outcome of my pet's surgery. However, I am passing along the information to my sister-in-law (a cat-rescue person who is also a nurse), and perhaps it will help someone else who may experience the same problem. The doctor who answered my question was amazing, and while it didn't come it time to change the outcome of my situation, it is reassuring to know the caliber of Vets/Doctors that you have at JustAnswer. Thank you for being there. Alice H. Jacksonville, Fl.
  • Wonderful service, prompt, efficient, and accurate. Couldn't have asked for more. I cannot thank you enough for your help. Mary C. Freshfield, Liverpool, UK
