About a month. After a male cat is neutered, the time it takes for him to completely stop urinating is about 1 month to half a year. Depending on the age at which male cats are neutered and the hormone levels in their bodies, their recovery after neutering will also be different. Generally, male cats will gradually stabilize in about 1 month to half a year, and the latest one will have a recovery period of 1 year. Because the hormones produced before sterilization take a while to disappear, cats will still be affected by hormones and urinate randomly after sterilization.

How to deal with cat urine:

1. Clean up the traces of cat urine. Cat urine contains special substances that cannot be completely washed away with water. Humans cannot smell it, but cats can still smell it, and they will follow the smell and try again. Pet disinfectant needs to be used to completely remove it.

2. Buy a variety of cat litter and put it in different cartons at the same time, and let the cat choose which one he likes.

3. Clear all obstacles on the way to the toilet.

4. Give the cat a toilet with a large space. It is best to have a length and width 1.5 times as large as the cat's body, allowing the cat to easily turn.

5. After vigorously cleaning the area where the cat has peeed, you can spray some DuPont Virgo disinfectant to deodorize and disinfect.
