Thanks for your response, No, it is not something I have addressed with the vet so far, because I have managed to keep it under control with supervision, but will be brought up next time I visit. Right now they are playing hide and seek amongst themselves so there doesnt seem to be any problems...
I have 2 cats, one super energetic,Tiggy and the other pretty normal, Moo I try my utmost to give them an hour of interactive play a day, and like most cats they have their preferences of toys.
Moo will always end up chewing up whatever toys he has an interest in, and will tear bits off, eat...
