Hi,
I just found a maroon colored poop in my litter box, is this normal? I am quite worried. It doesn't smell, it doesn't seem to have left any blood in the napkin I picked it up with...I just don't know what it could be?

Last 3 days I have fed one of my cats chicken (raw) and another one of my cats horsemeat (raw) and chicken (raw) and fish (raw)

Thanks
Melissa
