One way to find a reputable breeder of Sphynx cats is to check with breed-specific organizations, such as the International Cat Association (TICA) or the Cat Fanciers’ Association (CFA). These organizations maintain lists of breeders who are members in good standing and who have agreed to follow their code of ethics.

Another approach would be to ask for recommendations from your veterinarian, or from friends who own Sphynx cats. Additionally, you can look for online reviews, for example on the internet or in social media, from people who have purchased cats from a particular breeder.

When visiting a breeder, ask to see the living conditions of the cats and the cattery. Reputable breeders will have cats that are well-cared for and kept in clean and safe environments. Additionally, ask about the health history of the cats and their parents, and also about the overall lineage of the cats. A good breeder will be able to provide you with detailed information about the cats and their background.

It’s also important to meet the parents of the kitten if possible, as it will give you an idea of how your kitten may look like when they grown up and what personality traits they may have.

Lastly, bear in mind that reputable breeders will not be always the cheapest option, but investing a bit more money into buying a healthy and well-cared Sphynx cat will certainly pay off in the long run.
