We have an injured ACF that I'm getting worried about. He had jumped from his tank one night through a tiny opening, and was apparently attacked by our cat because he was placed at the foot of our bed the next morning, very far from the frog tank. He was dried, covered in animal fur, and not moving. I figured he was dead but saw one kick when I picked him up, so I put him into a small tank of clean water after removing all the fur wrapped around him. Amazingly, he was swimming around again within about a half hour. So I placed him back in the main tank with our other frog. But then I noticed his hands (front feet). Both hands were curled and he was struggling to swim. After a couple days I then saw our other frog snapping at the hurt one and saw that all his fingers are gone.
I'm guessing that the injuries from the cat attack, or the other frog attacking dead skin, caused this to happen. This was just a couple hours ago. I have moved him to a temporary tank with clean water for now. And he is still swimming and seems to have no other obvious wounds. But I have no idea what to do about his hands/missing fingers. Should I wait to see if the they regenerate? If so, how should I care for him until then? And I hate to consider euthanizing him, so I'm open to any suggestions. Please help.
