Some cats push things off tables out of curiosity, to get attention, or because of their hunting instincts. It’s a mix of exploring, having fun, and sometimes just enjoying the reaction it causes.
You may want to consider buying them things for entertainment and relaxation such as the Mewoo - Playful Paws Pet Activity Cushion, helping to redirect the playful behavior while also serving as a cozy nook.
