Cats and food. Bought some different stuff for variety. They both wolf it down. For about two weeks. Now Bad Cat just sits there and refuses to eat it. Obviously, having waited for me to buy two big boxes of the stuff.
And stop pooping in the house*. God, the stench permeates and my office is on a mezzanine level and doesn't have a door to shut it out.
*they're both doing it now, I did blame the weather but I think it might be foxes putting them off. I'm sure they've made a den under the summer house and often lounging up there in the sun. Anyway, I can't poop when a fox is looking at me either. Well, I've never tried doing it in front of any woodland creature, but you know, any audience is offputting.
