Tonight i removed the tissue where he urinates, and it has a pinky tinge to it, on all of the pieces
He seems fine otherwise running around, but is eating slightly less and drinking slightly more.
Is it possible that its blood?
How long should i keep an eye on it before taking him to the vets?
EDIT: I have not given him any beetroot, i have only given him the usual dry mix and the leafy nature mix
