I think stoats are smaller. From what my gf described ( she was apparently chasing it out the chicken coop when I pulled up today . Apparently this is what it looks like so long tailed American weasel
Anyhow the trap is only 6"x6" wide and tall and 34" long I think due to the outward swinging doors had to make it longer. Not to mention I wanted to have something I could use on other critters ,fox squirrels ,grey squirrels, smaller skunks, mink muskrats ,barn rats ect. Also since coyotes coon and other critters will try to get at the trapped animal out alot of times I had to make i
