Persian Kittens ® Persian Kittens ® wants you to be happy with our kittensl We guarantee NO problems, and offer this health guarantee. At six weeks kittens lose antibodies because the immunity which was provided by it’s mother from nursing starts to wear off as a kitten is weaned. When our kittens are six weeks old we have all kittens examined by a licensed Veterinarian. Due to immunization controversies, we no longer immunized our kittens, We leave that up to the new pet parents to do if they wish. We do provied a schedule of immunization recommendations. We keep detailed records of exams and kitten development, and provide it along with a Health Certificate from a licensed Veterinarian, along with Persian Kittens ® written Health Guarantee to new pet parents.
