No root canal for me today. The dentist's receptionist called me this morning to report that the dentist's cat bit him yesterday and now his hand has swollen up like a sausage.
The same thing happened to me a few years ago. I was goofing around with one of our cats and he got a little bit out of control and bit me on the hand hard enough to reach the muscle. Cat spit is so toxic that by the next day my hand was three times fatter than normal.
Cats suck sometimes, but they're still smarter than most dogs.
