 The Merrimack River Feline Rescue Society's low-cost spay and neuter clinic, the Catmobile, will be rolling into a town near you. We are taking reservations now for adult cats and kittens. We spay and neuter kittens over 10 weeks of age. The cost is $100 for female cats and $75 for male cats. In addition, the package includes a rabies vaccination, exam, flea treatment, ear mite treatment, and a nail trim.
