We have a 2 year old female rabbit, she was spayed a few months ago. This week we found a considerably large lump on her abdomen right between her legs. She has not pooped in about 4-5 days, she is still eating and drinking. We took her to the vet, and they did an ultrasound to confirm there is indeed a mass, but we don't know what it is. We won't be able to afford surgery, so we are just looking for some answers! If anyone knows what might be going on please let us know. Thank you!!
