Greetings,
Pink, you might want to try Rescue Remedy; I have used it on both Scooter and Mr. Boomerang. It is completely safe; you can put it on their ears. I bought the first bottle at the local health food store; then found it on Amazon for a lower price. It really calms my two down. I give it to Scooter before thunderstorms, and I give it to Boo when he wants to go outside to hunt or fight because he hears animals.
All is well here. Let's keep on keeping on.
