What happened to my male cat? Is it estrus?

The symptom you described is estrus. Haven't you done this before? Male cats in heat bark and pee everywhere. It must have never mated before, has it? Nowadays, animals sometimes eat better and their endocrine will be disordered. So the above symptoms you mentioned appeared in estrus. I suggest you wait until this time to take your cat to a regular pet hospital for a small sterilization operation. The cost is not high, and the operation of the male cat is simpler than that of the female cat, and it will be fine after recovery. Don't give it hair such as beef, mutton, fish and shrimp after operation.

You're right. It's not safe to give it away, and I'm worried that others will treat it badly. The only dependence of a small animal is its owner, so you can't abandon it at this time. Go to the hospital for consultation and wish the baby a speedy recovery.

My cat puts cat litter in a basin and teaches it to walk by itself.
