Sequester a room for the cats. We use baby gates set so the cats can get through but the dogs can’t. For one room, the side of the gate leaves enough room for the cats. For another room, the gate is up off the floor – cats can go under.
In our old house, we had a room set so the door only opened wide enough for the cats to get through.
We used to sort of do that. But really, I’m not going to close off a room just to feed two cats.
When we did, It was a piece of plywood with a hole cut in it. The dogs figured it out quite quickly.
I really liked the Hol storage cube that Boscibo pointed out (the lattice storeage box). But it does not seem to be available anymore.
I’ve also though of just a big plastic ‘tote’ suggested by usetobe. At least a clear one would let light in. But, my experience with them has been that the lid can be a bit of a pain to put on and off. Not really designed to do it every day. I’d like a lid that just flips up, in goes a cup of food and off to work you go.
My folks put a shelf just off to the side of the basement stairs up near the ceiling. Hard to describe…level with about the third step down. Kitty could walk out onto the shelf, doggies couldn’t. People access either from the stairs or from below, depending on accessing person’s height.
