Playing with an iPad or tablet is actually good for cats but be sure you don’t leave it out 24/7 or they might get bored. Also mix up the games. One day it’s bugs, then switch to mice, or birds, or fish. Variety is the key to a happy kitty.
I’m the person at the restaurant who is always letting her kid play with an iPhone or an iPad in hopes of keeping the peace, and even though my cats are not dining out with us, they’re also allowed some screen time back at home. How? I have apps on my iPad for my cats, too. Because. Why. Not.
