WebMD also recommends Valium, a drug popular among human and cat behavioral therapists for reducing anxiety and promoting relaxation. All Feline Hospital notes that Benadryl can be used as a feline sedative as a last resort as cats are generally opposed to the over-the-counter medicine's taste. Since Benadryl can easily be obtained at the store, it is a popular option for those who do not have time to get a sedative from the vet before going on a trip with their cat.Learn more about Cats
