Cat Shelves

Been having some issues with cat fighting / aggression. Came up out of the blue, with two of our cats who’ve been together for years. Our lover boy Ari is being a terror. I think that part-Bengal is showing. So, I’m in the shop working on shelves for the cats. Luckily, our dining room has some “lovely” wood paneling, so putting shelves in there will not distract from the ambiance.
