I feed only HALF a 3 oz can at a time, and often my boy doesn't finish that (and he's BIG).
But to feed, you might try what I have in my kitchen. I have a plastic "boot tray" (you can find them anyplace, but I got mine online for about $2). It's a heavy plastic, about 2 feet long and a foot wide. It fits nicely next to my fridge, and there's room for 3-4 plates or bowls on it. Since it has a lip all around, the cat doesn't knock anything on the actual floor. And the tray can be easily cleaned.
As others have noticed, the odor will be much less in the kitchen than in the smaller bathroom.
