Anyone out there know of a natural or herbal medicine to help a stressed out cat. Since Thanksgiving there have been several things that drove my 2 1/2 yr Male crazy. He used to be a real cuddler but after 4 dogs in the house brought by our houseguests and obtaining a new kitten he is licking all the fur from his backside and is really tense when we cuddle him.He hisses and spits at the new cat then runs away like he is scared. He even hisses at his sister if she startles him. I was thinking of valerian,but don't know if it is safe for cats. Any suggestions would be appreciated. BTW the dogs are gone and we will rehome the kitten if we can.She was a rescue.
