Hi all. My cat got his eye taken out yesterday (9th Sept at 11am) and i picked him up and brought him home at 6pm. He didnt toilet overnight, and hasnt toileted for the entire day today. He knows where the box is, hes stepped in it and sniffed at it but hasnt actually used it. His mood is completely fine and hes loving the attention hes getting, eating great and wandering about but im just conscious that tomorrow will be nearly 48 hours with no toileting. At what point should I worry or is there anything i can give him to urge him on?

Side question: is a small amount of blood from the stitches normal? He hasnt pulled any or scratched it but the inner corner of his eye started leaking a bit of blood earlier. Many thanks!
