Well I'm hoping if I shoo him he won't return. The first I saw him I thought that's a nice cat. Then he made a strange lurch with his back, I thought is he ok. Then he did a shit. Sniffed it and left. Couple of days later caught him from kitchen window again midway through a shit this time, again just watched him like a prat. And now again tonight but by the time I realized he was shitting it was too late. It wasnt in the garden still when I opened patio doors.
Can't wear this though, nipping it in the bud.
