My mom in laws cats LOVED getting into the plants and knocking dirt all over. She tried spraying them, swating them, puting smelly stuff on the pots to discurage curious cats...nothing worked. Finaly she gave up and the night she decided to, we all woke up to multiple crashes. The cats knocked over EVERY PLANT in the living room and kitchen. Broke two pots and dirt was everywhere.

They've never gotten into the plants again though!! Guess once was enough for a cheap thrill...
