How can I tell if my male cat is in heat and what are the signs to look out for?

Male cats do not go into heat like female cats do. Instead, they are typically ready to mate year-round once they reach sexual maturity. Signs that a male cat is ready to mate include increased vocalization, spraying urine to mark territory, and aggressive behavior towards other cats. If you notice these signs, it's best to have your cat neutered to prevent unwanted behaviors and potential health issues.
