Hello Emery. Hello Cooper. Welcome to Purrs.
How disappointing to feel the breeder has been less than honest.
It's possible there has been a genetic throwback along the line. It can happen in any breed, dog, cat, rabbit etc, but normally a breeder will spot this and sell as a pet only. Was the breeder TICA registered? Did Cooper come with full papers? If not, it's pretty hard to imagine you'll make much headway challenging the pedigree. There are a lot of backyard breeders out there trying to pass off mixed breeds as purebred, and often don't provide any papers, either for the parent or offspring.
If you bought from registered breeder, you could approach them with your concerns, and if necessary could raise a complaint with TICA if the breeder doesn't offer a satisfactory resolution. Presumably Cooper is a much loved member of your family, so you'd need to work out what would be the outcome you'd prefer by way of compensation - e.g. pick of another litter, or a partial refund.
Anything, cat, car, carpet, when advertised and sold must be fit for purpose and as described, though I balk at saying that about any transaction involving a living thing, regardless. Sounds so heartless, doesn't it?
You could ultimately bring a claim against the breeder in the Small Claims Court to try your case. You can do it online, and its a relatively straightforward process.
Do post pics if you can. We'd love to meet Cooper, who sounds adorable whatever he is, or isn't, bless his paws.
