My 6 year old female cat has been battling severe constipation since November. We first tried Lactulose, which made her sick. Then we got two enemas (one sedated) that seem to reset her clock, however she was still pooping on the floor and not the litter box. We were put on royal cabin fiber response diet which has helped, but still missing the box. We have water fountains and she pees regularly so dehydration is not an issue. Blood test work up came back very normal. We finally resorted to prozac to see if she has anxiety from the box and failed attempts prior, and we went 3 days without an accident. A few moments ago, she had an accident and something looks so incredibly off about this. Has anyone experienced something similar? Sorry for the graphic image... I may need to try another. Vet.
