This lifts mealtime off the floor and onto the wall, which is exactly where a cat living with a dog wants it. Your cat eats and drinks in a snug spot that a dog simply cannot get to, and the approach up to the food taps the same foraging drive that keeps them mentally sharp. Dinner becomes a small hunt rather than a bowl on the ground.When the meal is done, the built-in lounge gives them a comfortable place to settle and digest. It is designed for studs at either 16 or 24 inch spacing, so installation stays simple.
