How can I stop my cat from peeing on everything?

I have a cat who pee's on everything how can I stop that?

If the cat is not fixed, you should take him to the vet and have them fix him. Cats, especially boys, who are not fixed tend to spray on things.

Also make sure his litter box is somewhere that he can easily find, and make sure it is clean. Cats usually don't like going in a dirty littler box, so if it is too dirty, they will often just go outside the box instead.

If you have more than one cat, you could try getting a second litter box. Some cats don't like to share.

Good luck !!

put her out side or him out side or if you see them about to pee tap him on the head and say no and take them to the litter box every time and keep doing that till he/she learns

well if it a male you need to get him fixed because he will spray
