Here are some general guidelines for when to neuter male cats:
* Around 4-6 months old: This is the most common age for neutering, as the cat is usually old enough to handle the surgery and will have fewer hormonal issues.
* Before they reach sexual maturity: This is important to prevent unwanted pregnancies and behaviors associated with hormones, such as spraying urine.
* If they are showing signs of aggression or spraying: Neutering can help reduce these behaviors.
However, it's essential to consult with your vet to determine the best time for your cat based on their specific health and situation.
