We noticed some watery stuff w/ blood in it. I thought Winnie was for some reason going into heat (she is 6 1/2 months). I lifter her tail, and it made a weird noise, and also she had mucus coming from her rectum (if that is the correct term). So, I called the vet, and they were able to get her right in. They did a fecal on her, and it was not parasites, but colitis. I had mixed some of her Iams kitten food in with a sample of felidae and innova. It was not a lot, maybe just half a cup at the most. So, that is what the vet said caused her problem. She is on amoxy drops for 1 week and Flagyl for 5 days. Poor little girl ........
