I created a room designed as a "Cat Sanctuary". Knowing that mischievous cats jump and walk over almost anything in game, I strategically placed shelves to form a "feline highway". Unfortunately none of the cats showed any interest, let alone use it.

They don't normally jump up and walk on shelves, so next I tried using kitchen counters. Still no luck. I figured when I started making the room the highway probably wouldn't work, so I'm not surprised.

What I'm wondering is, if it would be possible to create a mod that would let the cats use their highway. Or would it cause chaos in the rest of the game. Can anyone help me with this?
