Cats like to hide when they are sick. Don't want to let the owner know. If your eyes are red, swollen or have excessive discharge, they may be infected by bacteria. If a cat suddenly becomes very lethargic and always stays in the cat's nest, the owner must carefully observe its mental state.

If the cat is a clingy little goblin, but suddenly one day it hides and disappears, then this is a bad sign. If it's because a stranger comes to the house or you move to a new house, don't worry too much. Just give the cat some time to adapt. But if the cat hides for no reason, then you need to pay attention. Most cats are not willing to let their owners know when they are sick.

If your cat’s eyes appear red, swollen or have excessive discharge, it may be a bacterial infection. If the fluid secreted by the eyes is greenish or yellowish, the owner should pay attention. This is likely to be a bacterial infection. If you don't pay attention to it for a long time and don't take your cat to see a doctor, your cat may be at risk of going blind.

Cats usually love to sleep very much. When the owner is not at home and not playing with it, it may sleep. But if you suddenly find that the cat is always in the nest within 24-48 hours, you should pay special attention. At this time, they are likely to have a cold, fever, or other viruses. At this time, the owner must carefully observe its mental state and even its heartbeat.
