What is toy for a cat?
Plastic rolling balls, with or without bells inside. Ping-Pong balls and plastic practice golf balls with holes, to help cats carry them. Try putting one in a dry bathtub, as the captive ball is much more fun than one that escapes under the sofa.
Do cats like toys?
There's always going to be the individual cat who likes to play with a ball. But for the most part, the more a toy looks, feels, smells, and moves like prey, the better cats like it. They do have preferences, so it's best to offer choices: toys that resemble different kinds of prey like mice, birds, bugs, and snakes.
