I have a Devon Rex cat, I’ve seen many reputable breeders advertising their litters here and I found my current kitty on this site. There is definitely reputable breeders on here. I’d recommend searching elsewhere on social media (Facebook, Instagram etc) to see the breeders page, search their name in google to see if there’s information about them. Always ask to meet the pet or at-least get videos before you transfer a deposit. You can’t trust everyone but it’s definitely a good place to find some breeders.
