Jennifer Doll DVM has a non-paying job as veterinarian for Witty Kitties Inc. and Animals All About Inc., and essentially takes on almost every animal that no one else will, expecting to get nothing (including appreciation) in return. Sometime it is learn as she goes, with a treacherously steep learning curve.

Her paying job is as veterinarian and Medical Director for Iowa Humane Alliance, spaying and neutering anywhere from 30 to 55 cats, dogs, rabbits, rats, pot-bellied pigs, and guinea pigs a day. You'd think this is not possible without a high complication rate, but you'd be wrong. The clinic is just that good. Specialized training and a single-mindedness of the staff makes it so. Dr. Doll hopes to spay and neuter every pet until there are no more unwanted in the state of Iowa, thus putting her out of business.

After 26 years in practice, the last 19 in Iowa, Dr. Doll has met and wrangled her share of Feral Cats, Black Bears, Cougars, Giant Pythons, and Crocodilians. And that is the short list.

Despite injuries to her body and pride, she is not quite sure she is ready to stop.
