I've heard of it, never had it. Mr. Amber Cat bit me on two different occassions. Both times, the bites got infected. First time I was on antibiotics. Second time, I was in hospital for a week on round the clock antibiotic IV as the pills didn't cure the infection and there was a concern I would lose the use of the hand. Had this spa treatment of holding my hand in a whirl pool bath for 10 minutes, then the therapist ahs to manipulate it to keep all the "gunk" moving. THAT hurt more than the bite had!!!!
