I hear this question all the time. It boils down to our disposable society. People get rid of their cats when they move into places that don't permit pets. Or when they're pregnant because they're afraid the cat will suck out the baby's breath - an old wives' tale. I've actually heard of people who turned their cats in because "they no longer match the decor." One woman asked a local rescue group if she could "trade in" her two cats for two cats the group was placing.
That depends on what you want. If you want a kitten, know that kittens rarely come into rescue. If you want a health guarantee, you better try a reputable breeder since we usually don't know the cat's health history or genealogy. If you don't mind an older cat or one with special needs, a rescue might be just for you.
"How do I find a reputable breeder?" By asking questions and being knowledgeable. Do research. Ask people. Go to cat shows and see whose cats are winning. Make sure they have a sterling reputation and references. Run if they don't have a contract for you to sign. This is for your safety as well as the cat's well-being. Not all breeders are reputable and sometimes reputable breeders lose control.
"I had read all about how social Cornish Rexes are, how happy they are to interact, how playful and active they are, but these are adults who've lived with one person their whole lives. I can only think that they were well socialized as kittens, and that the natural Rex personality is to not only accept any human immediately, but to shower them with affection. Clearly human interaction is far more important to Rexes than territory.
"I have had some very outgoing and social cats in the past. But this is different. And while this may seem like sacrilege to confirmed cat people, I must say these are the most dog-like cats I've ever experienced. I heartily recommend Cornish Rexes to anyone--and don't worry about adopting an adult, if you'd rather go that route. I'm sure some are less effusive than others, and some might require more time to adjust to a new household, but on the fourth day since adding these guys to my menagerie, I have to say I am absolutely sold on this breed."
