Our Bengal cat George has been unwell lately. We've had him and his sister Gracie since they were weeks old, and now they're six. Lately he's been much quieter than usual except in the middle of the night when we're sleeping, and he's turned sullen (apparently) and aggressive toward Gracie, who's a sweetie. He's in the habit of grabbing her by the neck and holding her down, sometimes looking as if he wants to mate, though they're both neutered. Blood and urine tests at the vet haven't turned up anything, and we're in the process of trying some pheremone diffusers in the house to try calming him down. Today he's better, so maybe the diffusers are kicking in. Also the little guy goes on Prozac tonight. Maybe we'll mix it in with an evening martini.
