Has anyone ever watched those nature documentaries about the great apes where they groom each other, pick off fleas and ticks, etc? Well, since I was a young child, I have loved cats. All animals, mind you, but cats have a special place in my heart. Anyways, the poor cat having fleas biting them always made me angry, so I hunt them, running my fingers deeply into their fur looking for the little heathens. Gotten quite good over the years. Anyways, I should think it would be a good therapy, the interaction with the animal calms a person, lessens the pain a bit, gives one a good feeling to help your friend with their bitey problem, as well as giving your hands some therapy. It is somewhat gross I suppose, crushing the evil little buggers between fingernails or chucking them in rubbing alcohol, and one should wash yer hands after doing it, just because, but I think it might help anyone with hand problems. Lemme know if ya find some help from this. Later all, Smoke
