Thanks everyone.
It's only 188g but it's super skinny. I was assured several times that it was eating very well and that it was eating rats, but it looks like it should weigh at least 300g.
I don't get any resistance when I try to pop, I can actually feel that it is fully inverted and I see the scent glands that females have. I am going to have a local breeder double check for me though. I'm not comfortable probing and I have no experience at it, but the person I am going to take it to knows how to prob.
