You can teach an old cat, if the newest production at Las Vegas' Popovich Comedy Pet Theater is any indication. Six afternoons a week, ringmaster Gregory Popovich wows his audiences with a menagerie of more than 30 critters, including 15 cats and 10 dogs.
The showman's felines perform a variety of acrobatic stunts. In one, a cat jumps out of a "burning" building into a net held by a canine "firefighter."
Popovich claims to be the first entertainer in the U.S. to use trained cats on stage. Therefore, it's not surprising that, in 2009, he wrote the book "You CAN Train Your Cat."
