Indoor cats need plenty of playtime for exercise and activity. The most stimulating cat toys are interactive or electronic, like cat laser pointers, where your cat can chase a moving target with excitement. Some cat toys are also treat dispensing, meaning you can fill them with treats, and your kitty has to solve the puzzle to get the reward. These offer lots of mental stimulation as well as exercise. Check out the Leaps and Bounds Seek and Swat Snake cat toys or electronic wand cat toys for hours of fun.
