I've noticed that one of mine has started doing pink wees. During floortime, they have a box to go into lined with newspaper. They use this as their litter tray and it is here that I noticed that for the second day running one of them did a wee that had a slight pink tinge to it. I'm guessing this is blood. Is this like a guineapig "time of the month" or should I be concerned and take her to the vet? I'm going to make an appointment unless someone on here can assure me it is not something to worry about.
Any ideas?
