Castrating your cat
Male cats are usually castrated at 5-6 months of age. If not, they may begin to spray (scent mark) their territory – which means your house and furniture.
Also, unneutered cats tend to fight more outside that can lead to painful abscesses and wounds.
Feline AIDS is also spread through biting.
If unneutered cats tend to stray away from home looking for a mate they may be more prone to being knocked by a car.
Neutered male cats also make much more friendly companions.
