I found a frog that appears to have been attacked by a cat, there are claw marks across his back and both his legs on his left side are fractured or broken. I think he is a Southern Leapord Frog. His left back leg is what worries me most, it’s pretty bad. He still has feeling in his toes as far as I can tell. He is about 4 1/2 inches long if his legs were stretched out. Any advice? Should I amputate the leg and hope for the best or leave him be and hope it will heal on its own? It's broken where the knee would be on a person, so he wouldn’t have to lose the whole leg. He is currently in a 10 gallon terrarium with hides/water and I’ve given him a little food. Please help!
