The Dr said Toby had a slipped disc in his back, as well as a partially torn cruciate ligament in his left rear leg. He gets some nice meds and gets to relax in a cage all day whenever possible. If he jumps, runs, or anything else, he could fully rupture the disc - and that would result in his being put down as we cannot afford $6k for neurosurgery and recovery therapy... So a cage it is!
