I don't know about EVA being ...safe? ... for use in cats. I've never seen any studies done with it on cats. That and cats usually don't eat the bones of animals. Though they are carnivores... so i suppose giving EVA to a cat would be a LOT safer than giving it to a horse or a cow.

The calming stuff you are thinking of is Rescue Remedy. Last time i knew it is perfectly safe to give to a cat. I wonder if the lavender oil would be safe? The fosterer to the pup that i mentioned in another thread accidentally put too much on the first time and the pup was quite lethargic for about eight hours. (Not overdosed type... just tired.)

Poor kitty. At least he has a loving owner.
