My girls were a bit like that about water after the spay. But as soon as I moved the bowl over right next to them, they started drinking. I think they just didn’t want to move.
There would be several layers of stitches so even if the outmost layer of skin separates, it can be re-done if necessary. A friends rabbit licked at the incision (glue, no outer stitches) and it separated. At recheck, the vet wasn’t super concerned. She went on an oral antibiotic and the area had to be washed daily and the skin knitted back together over time.
You could attempt to get a look by transferring her to a counter top perhaps. Are you able to get her to hop into a carrier or carry her while she’s sitting in litterbox over to a counter top? Once they are up somewhere higher and not confident to jump down, you’ll find they are easier at picking up for a quick check. You may even be able to lift just her front legs to look at the tummy.
I know I’m probably being silly but I’d rather be safe and silly than a sad bunny mom with a hurt bunny.
Not at all! Sending out some healing {{{vibes}}} for your girl.
