The causes of cat hair loss range from innocuous to dangerous.
Hair loss is a relatively common problem for cats, and it can occur for a variety of different reasons. Some cats who experience hair loss only lose a little bit of hair, and others might lose all of their hair. The hair loss does not necessarily appear in any pattern.
Here are some potential causes of cat hair loss:
Certain skin parasites take up residence in cats and cause mange, which causes hair loss. A ringworm infection can also cause hair loss. If your cat's exposed skin is red, bumpy, or scabby, she might have a skin infection.
Believe it or not, cats can get allergies just like humans can. Whereas humans might get itchy and bumpy when we get an allergic reaction, cats might lose their hair.
4. Hormonal Imbalances
Hair loss is common in older cats that have been diagnosed with cancer. But if your cat does have cancer, you will probably see more symptoms besides hair loss, such as weight loss, trouble eating or swallowing, trouble going to the bathroom, and unexplained sores or lumps.
6. Mercury Poisoning
If your cat eats a lot of tuna, she could be losing her hair because her mercury intake is far too high. Mercury poisoning in humans has been documented to cause hair loss, and it can have the same effect in cats.
What should you do if your cat is experiencing hair loss?
It's a good idea to take your cat to the vet. The vet can determine whether your cat has a skin parasite, a thyroid or other hormonal problem, or cancer. If your cat has any of these conditions, there are meditations the vet can prescribe to address the problem.
To prevent hair loss from over-grooming, try to deal with the root problem which is your cat's anxiety. She may feel anxious because there has been a sudden change that she cannot cope with, she is not getting enough attention, or she feels insecure in her home.
If the vet thinks the cause is allergies, try to eliminate any potential triggers for an allergic reaction, such as fabrics, plants, and soap, if you give your cat baths.
