How good is Kitten's Joy? Rated at even money to win the John Deere Breeders' Cup Turf (gr. IT) on the morning line, he is the lowest-priced favorite for any of Saturday's World Championship races. Friday morning at Lone Star Park, the El Prado colt received a ringing endorsement from one of the top trainers in the world, Hall of Famer and multiple Eclipse Award winner Bobby Frankel."He's the best American turf horse I've seen in at least 10 years, maybe more," Frankel said. "I haven't seen anybody able to do what he does."Frankel trains Breeders' Cup Mile (gr. IT) morning line favorite Nothing to Lose for Ken and Sarah Ramsey, who are the breeders and owners of Kitten's Joy. There is a story going around the backstretch that Frankel liked Kitten's Joy so much when he saw him for the first time that he tried to get the Ramseys to give him the colt, taking him away from trainer Dale Romans. But according to Frankel, it's not true."It's an exaggeration," Frankel said. "I never hustle a horse from another trainer. I just said. 'That's a real nice horse. I would love to train that horse.' But it wasn't in a way that I wanted him."Kitten's Joy, a 3-year-old, has captured six of his seven races this year. In his last outing prior to the Breeders' Cup, he defeated older horses in Joe Hirsch Turf Classic Invitational (gr. IT), winning by 2/1 lengths.
