After neutering, it’s much less likely that male cats will spray. However, there are other behavioral causes of spraying, and these are just as likely whether or not your cat is neutered, no matter which sex your cat is.
These causes include stress or environmental changes, and can be frustrating to resolve. Remember, though, that urine spraying is not the only form of scent marking cats do. Even after neutering, you can expect your male cat to spread their scent by rubbing, rolling, or headbutting.
