My cats hair has been falling out now for a little less than a week and its starting to worry me. Its just falling out on his back, right next to his tail. I dont know what could be wrong. I was looking online and it said that this could occur if they dont have enough nutrients..but ive been feeding him the same thing for more than 2 years and nothing like this has happened before.
There are no other things happening, no redness, nothing..just hair falling out!
There are a lot of different reasons that a cat's hair can fall out including parasites, fungus, allergies, nutrition and even emotional issues may cause them to repeatedly chew at a certain area. You didn't say which food you have been feeding for 2 years. But it's still possible for the cat to develop an allergy to something even though it was ok before. It could be an allergy to the food or to something in the environment. It can even be an allergy to flea bites. But I would see the vet if it continues.
