One requirement when taking care of cats is keeping them occupied so they won't be bored. One solution to this is giving them toys to play with. Another is buying them catnip to make them relaxed and happy. Or maybe you can do both using the Meownooker Cat Toy Set.
The set includes a miniature table with a felt top and felted billiard balls filled with catnip. It's very likely your cats won't be able to stop playing pool all day (if you can count it as a game of pool, that is).
The Meownooker Cat Toy Set is created by pet goods shop Vetreska and is available over at their site.
