  • Nathan Horowitz
    D.V.M.

    Dr. Nathan Horowitz was born in the suburbs of Boston and grew up there, hanging out at a lake and helping take care of cats for a local rescue group. In his mid-teens, his family relocated to Albuquerque, New Mexico, where there is no lake but still plenty of opportunities to work with animal rescue. He was homeschooled through high school, spent a gap year abroad, then studied bioethics at American Jewish University in Los Angeles. While in L.A., he did volunteer work at an animal shelter and found a feral mom cat with 3 kittens living under the house he was renting. One of those kittens still lives with his parents.

    In 2013, he entered the University of Illinois veterinary medicine program. This was not a big surprise to anyone who watched him grow up and had the opportunity to see his deep empathy for animals. One of the family cats, Kaylee, joined him at school. Kaylee was soon joined by River and Zoe, forming a formidable feline triumvirate. While practicing veterinary medicine in the Chicago suburbs, he also adopted Saffron, a Golden Retriever/Setter mix, thus giving him an excuse to take long walks every day.
