I just got home from the vet after having my kitten neutered. Quick question...I received a cone collar? for my kitten, and was advised to keep it on for 10 days. Is 10 days necessary? He won't allow me to put it on, and I know he's going to absolutely hate it and he's probably going to cause more harm to himself with it (rolling over it, jumping with it on trying to get it off, etc). Also, since this is my first kitten, any other helpful ideas/suggestions are greatly appreciated. Thanks!
