The Merrimack River Feline Rescue Society’s Catmobile Program is a subsidized mobile spay/neuter clinic designed specifically for cats. Our package includes a brief exam, spay/neuter, rabies vaccination for cats over 12 weeks of age (weighing 1.5kg/3.3 lbs.), flea treatment and nail trim. Our two Catmobiles are each staffed by a veterinarian and two technicians and can assist up to 40 cats a day. The Catmobile covers the South Shore, Central MA,  Metrowest, North Shore, Merrimack River Valley, Boston, and Southern NH areas.

The cost for the package is $80 for male cats and $100 for female cats. 
Qualified Feral Cats are $35. All feral cats are ear-tipped.

We have limited slots available for ferals; please call or email to inquire.

Microchipping is available for an additional $20.


*Please note that we have now instituted a $60 fee for late pick-ups. This fee is not negotiable and we are not able to be flexible with lateness due to our tight schedule. 

We apologize for any inconvenience; please help us out by being on time for both drop-off and pick-up!


SPECIAL NOTE ON CATS AGES 5 and OLDER: While we will book cats over the age of 5 years on the Catmobile, please be aware that our veterinarians reserve the right to turn cats over 5 away on the day of surgery if they have concerns about the cats’ health. Our vet will make that assessment once she sees the cat the day of surgery. In addition, please keep in mind that for the safety of your cat, we strongly recommend pre-operative bloodwork ahead of time (at your own veterinarian) for any cat over 2 years of age.  This bloodwork cannot be done on the Catmobile.


Make check-in easier by printing our surgical consent form. Please sign and initial it and bring it with you on the day of your reservation. Also, Download our Catmobile FAQ’s for answers to all of your Catmobile questions, as well as important information about your visit.
