Is there an alternative to surgery for spaying cats?

Dr. Emmanuel Fontaine is a specialist in veterinary reproduction and talks with Dr. Susan and myself about if we can spay cats without doing surgery. At the end of the podcast we talk about the difference between ovariectomy (removing only the ovaries) and ovariohysterectomy (removing the ovaries and the uterus) in cats. What is more exciting than cat repro? Did you know that cats are inflatable?
