Pets for sale on the internet have been bait for scammers for years, and a York County woman recently became the victim of a pet scam that was very convincing.Munchkin cats are a relatively new breed of cat."Munchkins have tiny little legs, so they're kind of like dachshunds in the dog world. They have little tiny stubby legs, and their ears go down. They have a perfectly round head," Catherine Hendrickson said.Hendrickson said after she found Bella on a website selling munchkin kittens, the seller started asking questions that many reputable breeders would ask."The questions he was asking, 'Are you allergic? You cannot breed this cat. You don't plan on breeding it, correct?' Just stuff like that. So, those were the things that were convincing," she said. After Hendrickson agreed to pay $900 for the cat and shipping, she started to receive official-looking documents, like an adoption certificate and a sales agreement with the seller's Social Security number."This is a tactic to make people think, like, this guy's super real, and he's actually giving me his Social Security number. Someone who's trying to defraud me would never put that on there," Hendrickson said.While it was all very convincing, News 8 On Your Side checked it out and discovered all the personal information was fake.In the end, the cat never showed up.The seller broke off communication, and Hendrickson lost her money."You know, scams happen all the time, and this one just seemed so legit," she said.Hendrickson made her payment through PayPal and urges all consumers to be familiar with the PayPal plans that protect their purchases and those that don't.One major sign of a pet scam is a seller who will only communicate with you through text or email. If the seller won't even speak to you, it may be a scam.
