In case you’re bored at work and miss your cat, you might want one of these cat toys in a tube. The cat sticks its head out of the tube and when you touch it, it darts back down inside the tube to hide out of sight.
Then a few moments later, it peeks its head up with a meow. Not only can this amuse adults and little children, but also cats who might be curious what these fake cats are doing. If you put one of these on your desk at work, it can also amuse your co-workers and your boss so nobody will want to get any work done (which probably won’t matter much anyway).
