Castration

[kit_kat]

I have just collected my two kittens from the vet's after having their balls chopped off. Now one of them has started to mount the other one! This never happend before and I thought that castration was suppose to stop them wanting to mate?

Any one have any ideas if this is normal?

Ok thats understandable, I just thought it was a little strange as he hadn't ever done it before.
