Kitten diseases

Sad kitty

The young domestic feline can have a lot of trouble reaching adulthood. Your immune system, although it works at full capacity from the first moment you are born, still needs to be strengthened, but to do this, it must be exposed to viruses, bacteria and more. However, if basic care is not provided, or if the mother has infected him with a disease, any of these microorganisms can kill the animal.

For this reason, when we talk about diseases of kittens, the recommendation is always the same: go to the vet as soon as possible. You have to think that the kitten is very fragile, and if it catches, for example, Feline Immunodeficiency, it can have serious difficulties to recover enough so that it can lead a normal life. Knowing this, we are going to tell you what are the health problems kittens can have.

Diseases and infectious problems

    Hello, I have a baby kitten that is about 4 weeks old and I don't know what's wrong with him. Yesterday suddenly he could not move and I left him as I left him, he turns to his side, he has had seizures, he does not want to eat or drink water ... I do not understand what is wrong with him and I am very worried because it seems something serious and I do not want anything to happen to him since it is very small. I have taken him to the vet and they do not know what can happen to him although they do not think that he will improve. I don't want to give up so if someone could give me a second opinion I would really appreciate it. Thanks.
