Cats may enjoy ball pits, as they provide a stimulating environment for play. Some cats may be curious and enjoy diving into a ball pit, batting at the balls, or even using it as a hiding spot. However, individual preferences vary, so it's a good idea to introduce the ball pit gradually to see how your kittens respond. Ensure the balls are of an appropriate size that cannot be swallowed, and always supervise their play. Additionally, provide a variety of toys to keep their environment engaging and enriching.
