Found a little pool of red tinged liquid next to cats litter tray, he seems absolutely happy in himself and purring away when stroked.
I firmly squeezed down his abdomen and he showed no discomfort at all, not sure if it was urine or maybe a bit of blood hes sicked up after hunting.
We've put white paper under the litter to see if he does anymore overnight and if there's a red tinge.
Any cat owners or vets around for advice
