Engaging toys and activities for kittens include interactive toys like feather wands, laser pointers, and puzzle feeders, which stimulate their hunting instincts and mental acuity. Balls and small, lightweight toys that they can chase and bat around help keep them physically active. Climbing structures, such as cat trees and scratching posts, provide opportunities for exercise and exploration. Rotating toys regularly prevents boredom. Interactive play sessions with owners, using toys that mimic prey, can further enhance their physical and mental stimulation, fostering a healthy and happy environment for growing kittens.
