Our allergy test kit includes freshly brushed fur directly off our purebred adult Siberian cats; the parents of your future kitten. There is enough fur to test two people per kit. We also send printed instructions, and have a youtube video above further explaining how to perform your in home test using our kit. Feel free to fast forward the video to 1:58. Some things are out of date, but the allergy testing info is still accurate. The price fluctuates quite a bit throughout the year based on supply and demand.
