I found a tree frog this afternoon that I rolled up in my truck window.I pretty much severed his entire right back leg. Is there any hope for this little guy?? Can I nurse him back to at health? I know nothing about froggies, but I hate that he was injured in my vehicle and want to save him if I can. Is this a lost cause, or is there any hope they are resilient and I can keep him alive and well in an aquarium or terrarium? Any help is greatly appreciated!
