Hi guys. I got this lovely Mexican Rosy Boa a few weeks back and she's been doing well so far, but the more I look at her the more I think Morticia may actually be more of a Gomez. "She" has spurs and a long, fat tail. Probes female, but I've heard that probing is unreliable in rosies. Some people also say that on rare occasions females can have spurs. I'm more of a ball python guy, so I'm not really familiar with rosy boas. Any help would be appreciated!

A few tail pics, cloaca is near my ring finger:






Nice closeup of the cloaca:


Might be easier to see the spur in this one:


And this should give you a good idea of the length of the tail:


Also worth mentioning: the previous owners said this snake is 4 years old. So it's an adult rosy, but only weighs 160 grams. I'd estimate the length at about 2 ft, definitely nowhere near 3. Seems small for a female. I know Mexicans are smaller than other localities, but not that small, right? It was fed an adult mouse once a week.
