Looking for recommendations of which baby gate to get that had a cat door access. We will need to put a gate to block access to our basement for when our little guy is mobile, but we also need to have a cat door in it for our cats. Two of our cats are missing a back leg so they don't have the leg power to jump over it to get downstairs to their food/litter box. Anyone find one that didn't damage their walls, was easy to use and had the cat door?
