While many regular circuses are hotbeds of cruelty, where mistreatment of wild animals passes as “training,” cat circuses are something else altogether. The only way to get a cat to do anything is to make it a pleasurable and fun experience, and circus cats have trained humans how to properly put on a show. Gregory Popovich, in fact, has been trained so well that the cats who work with him don’t require him to give them treats — just praise for their efforts!
Popovich has even written a behavior book for humans. Ignore the fact that it is called You CAN Train Your Cat — trust me, your human will be doing all the hard work, not you.
Here is another circus video from Russia. These cats look like they are really enjoying themselves — they are eager to do their tricks, even the final one, who does something that I consider really scary!
