Any suggestions? Treasure never calms down. Chamomile and other calming agents sold for cats don't work. Playing with him doesn't work (just gets him more wound up) and he's so bad that Sopdet now runs the minute she sees him (and she's very playful) and Shaman just told him off with a hiss and swat in the face. I feel sorry for him but it's hard to believe a 5 year old cat acts like a 7 month old kitten. Toys don't wear him out and he isn't interested in catnip. TBH if he was a human I'd find him a bit annoying and always under foot.
