I had pondered the Feliway plug in but was concerned that it might adversely affect my other cats, which are already about as content and calm as you'd want a cat to be, heh. Of course, they only go in the bedroom to visit Apple (the cat in question) or to sleep with me, so it would probably be all right? Bach's rescue remedy cream is excellent, so perhaps I will look into their oral homeopathic remedy, but unless I can hide it in a treat I don't think it will work. =P
Thank you for the advice. =D
This is a tough one. You could try Feliway wall plug in. Feliway destributes a feline hormone into the air and can give cat's a feeling of well-being. You could also try Bach Flowers Rescue Remedy, oral homeopathic remedy, but you would have to place this in his mouth three times per day. There are also other holistic products such as: Shen Calmer available from Jing Tang Herbal by prescription from your veterinarian but this is also oral. Other products available from your veterinarian include anti-depressants, and tranquilizers. Behavioral modification is also possible but it may take several years, and may not be effective due to his long ferral history.
