MalsiPree Robotic Interactive Cat Toy

$8 off


What? This is Prime Day on the Internet and you think we'd leave you without a cute cat robot? Of course not. This device is a set of wheels designed to annoy your kitty. What could be more fun?

So, some pets will love this and others won't. When I got my little dog, I planned on building it all sorts of robotic gadgets. I was going to make him a robotic car, a mech suit, and so many other things. But Pixel doesn't like plastic or mechanical things. At all. He just likes yanking all the stuffing out of his little stuffed animal friends. But your cat just might like chasing a robot all over the house. More to the point, you might like watching your cat chase a robot all over the house. 

Go ahead and get it. You know you want to.
