I used to have a diluted tort...SO PRETTY!! She was gorgeous...
Also, my first kitty was a straight tort, deemed Mama Kitty because she was a stray that kept having litters (this was about fifteen years ago...and she was the neighbors technically, even if she did bring her kitties over to our house every morning, after he'd brought everyone back to his porch every night...so we couldn't just go get her spayed). It's funny...people used to think she was ugly...but I thought she was GORGEOUS!!
And Katie with that diluted tort color...oh, DREAMY!!
And then we had a straight calico...Nicki...softest kitty! She was really grumpy, and it took me a LONG time of sitting on the floor, getting her to adjust to me being around, and finally she just resolved herself to the fact that I wasn't going away until she let me pet her...what a gorgeous cat. Her coloring reminded me of a court jester's costume...one paw orange, the other one black, and every following part of her was switched to be the other way around...she was so pretty!
But yeah...I'm partial to the tort/calicos...they're really special kitties.
Oh, and something else interesting...Mama Kitty (the straight tort) would mate with an orange tabby in the neighborhood (named Mr. Morris, hehe), and they would create all rainbow colors of tabbies...and tuxedos...broken tabbies...just a whole slew of different colorings. It was really interesting!
