There are two reasons. One is that the male cat has not been neutered. If the male cat is not neutered for a long time, his tail will grow fat particles, turn black, and cause hair loss. Get it done quickly, otherwise the cat will become a cat again. Cancer will only happen, female cats will get uterine fibroids, and male cats’ buttocks will rot quickly, so it’s done quickly, and it takes very little time. Male cats recover very quickly, and they will be fine the next day after the treatment. It will heal in about a week, and it will remove the stitches on its own.
Second, take a bath with washing powder. Humans can’t bear to wash it separately. It’s also embarrassing for your mother. You want your cat to be cleaner. , turned out to use the wrong shampoo, haha, rinse him with water, but as you said, this situation is more serious, it is better to go to the hospital, there is a special cleaning solution, otherwise these two things will happen together. Cats are quite dangerous, maybe... don't use sulfur soaps, they are all irritating, just rinse them with clean water. If that doesn't work, it's better to go to the hospital. You may be busy too, your mother You also don’t know how to take care of cats, so go to the hospital and understand everything at once, so that you can be relatively worry-free and the cat can be treated as soon as possible.
