Fed the cat this morning and one of the sachets poured out as liquid, instead of expected jellied meat. I binned its contents and put bin bag outside, and immediately washed the cat bowl and food tray. I also sprayed odour neutraliser spray around and cleaned the floor under the tray. But the rank smell is lingering, despite windows being open. It's really really foul. Do we just have to wait till it dies down? Any brilliant suggestions?
