Cav-A-Jack History

The Cav-A-Poo, or Cavy Jack, is a cross between the Cavy and the Jack Russell Terrier. The Cavy has been a popular pet for many generations, but the Jack Russell is not. The spontaneous mutation that created this hybrid occurred in 2007. The offspring were described as resembling the offspring of a Chihuahua and a Beagle. (By the way, this is known as a Chibhua or a Chug, not a chupacabra which is what it sounds like.) The Pinguicula genus (also called the Butterwort family) is a group of carnivorous plant species in the Lentibulariaceae family. They are native to the Americas.
