Pairing the golden gradient layer with the Ragdoll will result in a string of cats. Golden layer cats and Ragdoll cats are two different breeds. Kittens bred from mating are likely to carry hereditary diseases. If the kittens have serious defects, it may cause dystocia for the female cat, and the appearance of the kittens is uncontrolled. ​​​​​​​ Kittens produced by mating two different breeds of cats may carry genetic defects, or they may be healthy. Not all cat breeds are bred from the same breed. For example, Fold-eared cats can mate with British Shorthair and American Shorthair, and the resulting kittens will all be Fold-eared cats, but Fold-eared cats have genetic defects.
