I just joined their Facebook group. I have had two CH cats so far: RB Diva, and current CH incumbent Spike. Both black cats, but there the similarity ends! Diva was very petite, and had severe CH. She "trained" us to help her with the litter box by standing in front of it and yowling for us to hold her while she did her business. Spike, on the other hand, is a 16 lb giant of a tom, who loves to sit on my lap, and has a meow that sounds eerily like "hello"!
