Okay, so there is a Rescue in Huntingdon, KY that goes to the Guardian Animal Center in Flatwoods, KY which the woman said isn't too far from Louisville. She said they accept Care Credit but you have to set that up with them over the phone when you call and make the appointment. She said it's definitely worth the drive because they actually go over husbandry and do routine habitat instruction for new reptile owners, so that actually sounds pretty promising.
She also said that there is a large Animal Hospital in Louisville called Jefferson Animal Hospital that used to see Reptiles, she mentioned a Dr. Pam Williams by name, and they take Care Credit, but she wasn't sure if they were still treating animals other than Dogs and Cats, as the local Reptile Rescues and Breeders stopped using them for some reason, they all go to the Guardian Animal Center in Flatwoords, KY now...
As a third option, she highly recommended the Shively Animal Hospital in Shively, KY, and a Dr. Mary Fuchs, who is their Reptile Specialist and owns Reptiles herself, she apparently knows her stuff, but she wasn't sure about the Care Credit, you'd have to call them and ask them. She seemed to really highly regard this particular Vet.
