Both cats are Ragdolls, a breed developed in the U.S. in the 1960s. Imzadi was a female seal point and 3 years old in these pics. Riker (Mr. Imp) was a male blue mitted with blaze and about 1-1/2 years old in most of these pics.

Sadly, both Imzadi and Riker had to be euthanized a week apart in August 2005 due to feline hypertrophic cardiomyopathy (HCM), a disease that's a big problem in the breed.
