Catrick is being neutered this week. He is six months old, and his testicles are grown and ready to go. It’s minor surgery but I always feel sorry for them.
I usually have male cats sterilised at 6 months so that they are matured enough to be physically ready, but have not developed any tendency to aggression or spraying. Some people do it at 12 weeks but I prefer to let the cat grow first.
You can get Neuticles – testicular implants for neutered animals – to puff the scrotum up again. I am not sure why you would want that – maybe so Rover doesn’t feel emasculated at the dog park – but I have better things to spend my money on (sorry Catrick!)
