can someone help me in my back yard i saw some strange looking animal it has a tail of a rat but the rest lloks like a beaver, can some one give me answer.
I would agree - most likely a Muskrat (Ondatra zibethecius)....however if you're farther south (Louisiana, Texas..they're even in Arkansas and some states on the east coast) it could be a Nutria (much larger definitely more beaver-like)
