Clementine Small is one of our beloved Sanctuary bunnies. She is a victim of chronic bladder sludge. To treat this, she routinely gets fluids a couple times a week. Sometimes it worsens and she gets them on a daily basis, and I manually express her bladder until it is all out.
She gets significant pain meds and antibiotics during that period of time.
