This morning I found a small piece of otherwise normal stool with about an equal amount of bright red blood on the floor next to the litter box. It seemed relatively fresh, but I don't know which of my two boys it was from. Both have been acting totally normal today - eating, active, no vomiting.
I called the vet, and they had me bring the sample of bloody stool right over so they could analyze it. I'm waiting for them to call me this afternoon with some results. Currently I have each cat locked in a seperate bathroom with a litter box, wet food, and water. I am hoping to discover which one of the cats this blood came from.
Does anyone have any idea what might be causing this? I'm very worried...
ETA: Perhaps I should add, they are both 4 years old, indoor only kitties. They were both at the vet in the fall for check-ups and their stool samples checked out fine then.
