This may sound like a strange question, but is it okay for a stool sample to have litter on it? I have to take a stool sample with me to the vet tomorrow, and I tried to catch Walter in the act but I wasn't in time. I did get it fresh, pretty much right after he did the deed, but it was covered in litter. Is that okay?? Also, to clarify, I put them in the fridge until tomorrow, correct? I double baggied each of them and then put them in a disposable food container. Hopefully this works, b/c I HATE dealing with poop that doesn't come out of a baby's butt.
