Yes he had but I don`t know why. I had a cat that lived in my house part time and one day I went over to a friend`s house for the night. I was pretty sure that I turfed the cat out (hopefully, back to her own house) before I went but when I came home 24 hours later I realised that the cat had been shut in my house. I searched all over because I was sure she would have gone to the loo somewhere but there was nothing at all. That night when I went to bed, I found out where the cat had urinated - on my PJs which were underneath the duvet on my bed. I thought it must have been some sort of distress/separation anxiety.
