Dr. Jennifer Woll has nearly 20 years of experience as a veterinarian specializing in cat care. She earned a biology degree and has worked in animal hospitals in Illinois. She breeds Ragdoll kittens, which are born in a private maternity ward to reduce stress. Ragdoll kittens are born white and develop their color and pattern over two weeks. Ragdolls take up to 4 years to fully develop their size, weight, and fur pattern.
