Apr 24, 2017 - Allergies: They're the top cause of hair loss

Symptoms of other allergies include chewing on the paws or base of the tail, or scratching the ears
It's quite possible that your cat's abnormal amount of scratching is due to mental rather than physical reasons. Some cats incessantly scratch, bite, lick or chew, self-mutilating to the point of causing bald spots or lesions on their bodies. While this obsessive behavior can occur in any cat, Siamese and other Oriental breeds are the most likely to self-mutilate, and females more apt to do so than males, according to WebMD. Your vet might prescribe antidepressants or anti-anxiety medications to stop the behavior.
Parasites, including fleas, mites, lice and ticks, can make your cat itchy and result in scratching and licking, which with time can cause bald spots and even sores.
In the hot summer months, it's not uncommon for our feline companions to be shedding. There's fur on the furniture, our clothes, and perhaps in the form of a partially digested hair ball. A little shedding is normal. If you notice that your kitty is losing chunks of fur or if they are developing bald spots, then you may have a serious issue that needs to be dealt with. Feline skin is susceptible to many ailments. Here are five skin conditions that may be causing your cat to lose fur and scratch for relief! Some cats incessantly scratch, bite, lick or chew, self-mutilating to the point of causing bald spots or lesions on their bodiesAllergies can also cause hair loss or skin lesions anywhere on the body, including the belly.Like people, your cat can be allergic to food, insect bites, medicines, dust, or pollen
Cat hair loss and bald spots may be caused by the natural seasonal shedding, but may also be caused by other diseases. Bald spots may be self inflicted, as the cat can lick and scratch his skin excessively due to different conditions. The cat bald spot diagnosis can be done by performing a few tests, but a few additional symptoms may also help detecting a possible medical condition.Demodex: There are two types of mites that can cause a problem in cats. The mites live in the hair follicle of your kitten. An infection with this mite can lead to patchy bald spots, red or crusty skin. Your cat may be scratching, but infection with these mites is not always itchy. Pyoderma is a bacterial infection of the skin. There can be moist, red hot spots or sores with pus. They develop when the cat's immune system is low enough to allow the bacteria to grow in places where the skin has been broken like bug bites, animal bites, scratches, burns, abrasions, or rashes. The cat licks and scratches the area and a bald spot appears. The condition is treated with anitbiotics either orally or with an antibacterial salve. Treatment needs to take place before the infection reaches the blood stream and a more serious infection occurs.
The scabs on his ears started about 6 for so months ago... around the time that we got a puppy who likes to play with Buster. When they play Buster's head is usually in the dogs mouth but the dog is not rough, though I could see how the dog could puncture his skin and then maybe Buster just keeps scratching at it... I don't know. Is it possible for Buster be allergic to the dog or the dog's saliva, or even the other cat for that matter? I have tried putting a .05 cortisone spray, for cats, on not only his ears but also his paws and stomach. Even though it seems to relieve him a bit, mainly on his ears, he still licks at the sprayed bald spots causing him to vomit. And whenever he see's me with the spray bottle or the cotton swab he runs away from me... he hates it... I don't know if it hurts his scabs or if he just doesn't like me holding him down to put it on.I have just recently noticed that my 4 y.o. male cat his ears have little scabs on them and so does his neck and then I also noticed that around his eyes were a little inflamed and red. The red is blood, but it's not like dripping blood, but more like tinged and it just so happens to be in that sparce area of the cats head between it's eye and ear. There are no scabs or bald spots anywhere else on his body and he is his behavior is normal. At first I thought he was scratching himself w/his claws. His claws are very long. He does have a scratching post, however, he NEVER uses it. Preferring my boxspring, the end of the sofa or the rung on my banister. His ears did clear up, but now it's happend again and around his eyes too. My husband and I have both checked him for bugs, but found none and he is an indoor cat that has never been outside. What's wrong with my cat?So, a while back I noticed my cat scratching her neck fairly often and getting large bloody sores that would be bald ( I have found scabs with hair attached to it, apparently she was scratching it out in small clumps) Once the scab would heal the spot would be totally bald untill new hair grew in. Once the spot was completely healed a new one would show up. This went on for a while then the spots got smaller. Now, th spots don't go bald but I can feel the scabs around her neck and she is still scratching and I still find hair she has scratched out. Does anyone know what is going on?
