Animals from muskrats to foxes and larger gnaw off their own legs when caught in leg traps, and they don’t grow back. No biggie.
When one the farm, we needed to clear out a bunch of rats and I found one trap with just a leg in it, the rat had chewed off the leg to get away...another trap had only the rats tail in it....we also found out you have to tie the trap to something they cannot limp away with...we lost one trap and never did find it....another one was so gross I won’t even mention it.... they know what they need to do to get free....and do it...
