Hmmm Kalypso's poop was a bit bloody there for a little while. But she still only pooped in her litterbox and she wasn't licking her bottom. When Kalypso was getting it, it was because she was so young yet she was eating kitten food, cat food, and dog food and her body just wasn't use to it. But it went away a week later thankfully.

I hope that your Molly will be okay and that its nothing too serious.
