The old saying goes: you can pick your cats, and you can pick your toys, but you can't pick your cat's toys. Buy a cat a fancy new toy and she'll prefer to play with the cardboard box that it came in instead. Set out a tower for a cat to climb, and they'll stare at it and then walk away unimpressed. My wife had an old, scratched-up cat tree that has put in many years of service that, after all this time, the cats in our clowder have grown bored of playing in and sleeping on. We had it set up in the living room where it was ignored with prejudice. How do we make it more appealing? My wife gave it a Super Mario makeover, covering the ratty carpet with new fabrics invoking the familiar Mushroom Kingdom bricks, pipes, and piranha plants. Now we can't keep the cats off of it!
