This post is 100% serious, as I have a genuine concern with one of my female Couch's Spadefoots. I received her about a year ago, and she's a healthy girl. She eats every time food is offered to her, swims well, burrows frequently, etc. However, I've noticed that she "grips" her female cagemate.

My female does not have any nuptial pads, and I know that she is a female because A.) she does not have a throat sac that puffs out and B.) she has the correct sexual dimorphism to indicate that she is in fact female.

Has anyone seen anything like this, or any explanation? She seems healthy enough so I don't think it's some kind of after-effect of a disease, it's just weird.
