High pass filters

So when I think about gating I have to think about what, exactly, I want to filter.

Well, sometimes I want to keep the dogs from the cats, or more precisely the cats' food.

Sometimes I want to keep Skyler away from the cat litter box. This is an unfortunate failing of his, he loves cat leavings. It is like a smorgasbord for him. Or all-you-can-eat buffet. Yeah, I know. Hence the gate.

With the baby I want to keep her off the stairs, and sure, why not, out of the cat litter box too.

But do I want to gate the dogs from the stairs? The cats?

This is the gate we use currently to filter out the dogs from the area where the cat food is:It is metal, looks pretty good, is easy to use but childproof, fits a wide opening and the cats have a pass through that is not big enough for a mobile human.

In our house the litter boxes are downstairs so the cats must be able to pass easily, we all remember what it was like when Ole Pepe didn't care for using his box anymore.
