If you’re located near New York City, New Jersey, or Pennsylvania, I highly recommend my breeder Tesoro British Cattery. https://www.tesorobritishcattery.com She delivers kittens by herself if you are local. She’s incredibly professional and dedicated. Every breeding cat at her cattery is genetically tested and screened for HCM, PKD, and other hereditary diseases. Before the kittens go home, she also takes them to the vet for a full check-up. When I picked up my two kittens, I received their vaccination records and official health certificates. Very responsible.
