This video proves with no doubts that CATS are very skilled in learning new tricks. Wow !
Although cats don't seem to suffer loneliness like dogs, it is important to think about how they can pass the time when their owner is out. In addition to the usual things (such as giving them the opportunity to observe life outside the window) you can try to create a device that gives out food, stimulating the animal to a curious treasure hunt. Look at this cat and going "hunting" of his dinner.
