PayItFoward: Maybe it's time for the threatening part then, lolol.

I left him alone for like 2 nights (just at night, he had to care for 2 young orphan kittens) he couldn't do it, I was so sickened by the site of the litter box and that they hadn't aten enouch when I came back home both days.

I know he hates scooping litter boxes and such, but he will feed the cats about 40% of the time now, I try to keep him ready and know how to do things incase I ever can not do it myself for some reason.
I went away for about 4 or so days to Maine for a while so he had to care for 3 cats, ferret and a bird, he did a good job this time. I printed out everything he needed to know, and a schedule, plus I said I would kill him if anything happened to my babies while I was away. I also added that Asim will poo/piss on our bed if he doesn't scoop the litter box well enough, it was a good incentive!
