My little bun is usually a conservative eater, I will give her some greens and a small amount of pellets and she usually eats, waits some, and eats more. Eventually eating all of it. But yesterday when  I got home I notice her uncharacteristically docile, she has been laying down on the floor wedged between things. I found her between a baby gate and her cage, just wedged in between and when I went to move her she just went right back at it.

She also really loves her bananas, but she was not at all interested today.

I am thinking it could just be gas, she has gotten belly aches before but this doesn’t look like her. I was wondering if anyone knew what I can try to do to maybe relieve it before I just take her to the vet. 

Help!
