Bowls: The cats free-feed kibble, and get a little bit of wet food 2-3x a day. They won't eat a lot all at once, so if I don't spread it out, it goes to waste. Every time I run the dishwasher, I put the food bowls in, and usually the water bowl too, especially in summer, because it's humid and I don't want invisible mold to grow. Neither of my cats is interested in people-food at all, even meat. I use ceramic bowls. When they're being washed, the cats eat off antique china saucers. Because I have lots of unmatched china saucers and plates.
Water: Mine like to drink from glasses. I keep glasses of water beside the bathroom sinks (removed when guests are here!) and sometimes Leo comes and tells me that one of them is empty! Plus a bowl of water near their food. Not too near, or they drop their food and toys in it. I change the water every day, sooner if it's dirty. They both seem to drink a good amount, plus they get wet food with water in it, so I think they're well hydrated.
I cannot bear the thought of scrubbing out cat pans. When they get bad, I toss them and buy new. I know; it's horrible. But I scrubbed out cat pans twice in the driveway and I can't stand it. I clean the pans out once a day, more often if something especially aromatic is deposited. I have a covered pan sitting in an old plastic washing-machine-overflow-protector-thing in the little storage area in the downstairs bathroom, and another pan in my office, in a large plastic storage bin that I cut a door-hole in. The cats have room in the bin and on the plastic thingy to walk a few steps and get some litter off their paws, then they exit onto a doormat that pulls most of the rest of the litter off. It keeps the litter-tracking to a minimum.
Calli, what kind of litter box do you have, and where did you get it? That sounds very handy!
