Unfortunately I accidentally locked a (semi-feral) cat in our workshop on Tuesday, at about 3pm. He was found by a neighbouring business checking through our window because he was missing - fast asleep on the floor. They have a key and so let him out today (Thu), mid-morning.
So, he's been locked up from Tue 3pm to about 10/11am Thu, apparently without peeing or pooing anywhere. I can't get behind everything to check but there's absolutely no evidence anywhere, and no smell (he's a neutered tom).
I'm a bit concerned that I might have missed something and we hold our stock in there, so can cats go this long without toileting? Poor boy. But he did swipe me today and drew blood!!
