A poop problem
Hello! I know there are countless threads about out-of-box pooping but I didn't want to hijack one, since I have a more behavior-modification-type question.
For some background, I am fostering Tabitha, a 13-year-old who was rescued from a hoarding situation about a year ago, then placed in a few bad foster homes before a rescue group got her and I brought her home. She has asthma but gets an inhaler and isn't symptomatic. She also came to me with severe constipation, and it took almost 3 months to get her pooping consistently and with good form to the poops. She's always eaten Wellness wet food, with added fiber, and now goes consistently. However, the "going" is still an issue. While she pees in the litterbox every time, she has yet to land a poop in there.
She's been to the vet multiple times to rule out medical issues, and the vet feels it's entirely a behavioral issue. I've tried every type of box, every type of litter, Cat Attract, multiple boxes (she's in one room during the day when I work, so there aren't stray poops around my apartment to find) and an enzyme cleaner used every place that she goes.
Has anyone had success with behavior modification for this? Any advice is greatly appreciated!
