Well as some of you may know my cat has CRF. Part of the CRF is that she becomes constipated due to excessive urination. She already gets subQ fluids every other day, but today she was having a hard time with her bowel movement. Maybe she always does & I just don't happen to be awake or around for it. At any rate today she was going in her litter box straining to have her bowel movement (I know it wasn't that she had to pee, because she had just done that) & then after awhile she got out & threw up. I gave her some stool softener & then had to leave for school, I stoped back after my class to check on her & she had, had a BM & I palpated her belly & her colon area was empty, so I'm glad to report that she was doing much better, but my question is has anyone else experienced a cat vomiting when it was constipated? (I just have to say until my cat was diagnosed with CRF I never imagined I would know so much about her BM's)
