Opossum and smaller raccoons are the right size for that print, but it looks wrong. I don't know if you have them locally, but it looks like a ring tailed cat to me. I though I had some rats in my building where I worked/lived in NM. I would hear noise in the ceiling when I worked late at night (usually around midnight). Eventually realized that it was larger than a rat due to the amount of noise (then it left some tracks). Set a large box trap (humane) and caught it alive in the break room and had my peeps release it in the wilderness miles away. They are nocturnal...and good mousers and were keeping the population down...but it pooped on my desk (on papers like a nice kitty) so it had to go. After getting rid of it, the local rattlesnake population grew quickly (they were everywhere...even in people's offices) as apparently it was competing with them for food (mice).

They are not uncommon out west, but rarely seen as they are completely nocturnal. I have read that back in the day, some folks domesticated them to keep the mice down.
