Is there a real difference between the two registries? Some breeders double register their cats, so kittens would be eligible for either, some just register with one. Most breeder I've researched will send the reg. papers after the buyer provides proof of desexing (i know other countries typically neuter before the sale but it doesnt seem common in the US) I absolutely plan to have mine fixed, but is there really a point to registering a pet?
