Thanks for all the tips. I have two cats, one is 11 y/o male (about 10 pounds) and one is 6 y/o male (about 20 pounds). I've handled the litter box before by putting it in the second bedroom or an unused closet, but this tiny studio I don't have anywhere I can stash it out of the way. I'm also getting really sick of the litter tracked everywhere - with an added problem I've discovered at my new apartment, where I am on foot, and there is no where even remotely close to purchase cat litter. Closest I've found is a min of two buses away and having to cart the litter three blocks up a very steep hill.
I tried step 2, putting the box on the toilet, but as I was afraid, my big 6 y/o jumped in and it slid off onto the floor. So it is back next to the toilet while I figure out how to fix it so it willnot fly away.
