Recently purchased a feeding dish, having had problems with ants getting into my cats food. Far as I'm aware, this is the only product I've found that's small enough for a cat. Most are large-sized bowls for dogs.I've only had it for a few days but so far, my cat has only nibbled on her food. I'm not sure if the small moat that encircles the bowl makes her apprehensive. Time will tell. Worst case scenario I'll have to ditch this for a normal bowl and clean up the ant mess as in the past.It's not expensive so it might be worth a try. Every pet probably has a different outcome.
