Ok. when out this morning, in the 25-28 degree range (florida) and I noticed blood on the ground. Several days ago I had to put someof my mixed breed 3 month olds in a multi-hole rabbit cage, wire floor. They have been fine until last night. Well the gace is about 2.5 feet off the ground. My silkie was missing a toe, a naked neck missing the large missle toe and another smaller one and a Cuckoo Maran a mall toe. I am thinking frost bit and the toe was in the metal floor and simply broke off leaving the mess. The wife says a rats. I just can not see a rat haning upside down going after toes. What do you think.... O, they have been move to a differnet cage..
