Pet overpopulation is a serious problem. It costs the lives of millions of animals and costs communities millions of dollars a year. People in underserved areas can get spay/neuter services at reduced fees, subsidized by Dumb Friends League donors, when one of our mobile clinics visits their neighborhood.  We also partner with local animal welfare organizations in a trap-neuter-return (TNR) program for community (unowned) cats to help reduce the number of unwanted litters born and the number of kittens and cats brought to shelters.

We offer CAT spay/neuter surgeries for $10, including age-appropriate vaccinations (rabies and distemper vaccines). No qualifications are required to qualify for $10 cat spay/neuter surgeries.

We offer DOG spay/neuter surgeries for patrons who qualify for $50, including age appropriate vaccines (rabies and distemper vaccines). To qualify, please bring one of the following low-income qualifying documents when you check in:

• Quest or EBT card
• Paycheck stub (showing income of no more than $769 per paycheck) 
• Income-tax return form (showing income of no more than $40,000 per year)
• Financial aid award notice
• Unemployment check stub (with current date)
• Medicaid card
• Supplemental Security Income (SSI) ID or letter
• FDPIR

The Dumb Friends League appreciates the support of more than 150 local businesses that act as host sites for its mobile spay/neuter clinics. These businesses are truly friends of their communities by helping bring together the services we provide and the pet owners who need them. We have two mobile clinics:

The Meow Mobile clinic for cats

The Meow Mobile provides spay/neuter services at reduced fees, subsidized by Dumb Friends League donors, as well as vaccinations for cats that belong to people in underserved areas of metro Denver. The Meow Mobile is a partnership between the Denver Area Veterinary Medical Society and the Dumb Friends League. Veterinarians volunteer their time, working alongside a League technician and assistant. During its first five years of service, the Meow Mobile teams sterilized more than 14,000 cats.

The Lulu Mobile clinic for cats and dogs

The Lulu Mobile provides spay/neuter services at reduced fees, subsidized by Dumb Friends League donors, for pets belonging to people in underserved areas of metro Denver. A gift to the Dumb Friends League by generous donors, the Lulu Mobile is staffed by one full-time and one part-time veterinarian who perform 15 to 40 surgeries per clinic day. In its first three years of service, 13,947 cats and dogs were sterilized.

Host sites are needed for both vehicles. If your business, community center or church can offer a parking lot, call Tracy Koss at (720) 241-7088. This is a good opportunity to provide a needed service to your community. There is no charge to our hosts.

Frequently asked questions

How much does the spay/neuter surgery cost?

Cat spay/neuter surgery is $10. Dog spay/neuter surgery is $50. Age-appropriate vaccines are included in these prices. These fees are highly subsidized by generous donors to the Dumb Friends League and by many veterinarians who volunteer their services.

Who qualifies?

People with limited or fixed incomes who cannot afford to take their pets to a veterinarian qualify for these donor-subsidized services.

Who performs the surgeries?

Veterinarians who are licensed in the state of Colorado perform the surgeries. Some are in private practice and volunteer through the Denver Area Veterinary Medical Society. Others are on the staff of the Dumb Friends League. They have experience spaying and neutering dogs and cats in high-volume settings. They are assisted by veterinary technicians.

What do I need to know before I bring my pet for surgery?

• Do not feed your animal after midnight the evening before surgery. Water is OK.
• We operate on a first-come, first-served basis and do NOT offer appointments.
• The number of females and males we can take in varies at each clinic. Please note that this may mean that a person’s pet in line behind you could receive surgery even if yours does not because we have reached our daily limit of females or males. In this case, you will receive a rain check.
• Bring your pet(s) at 7:30 a.m. the day of the clinic. Dress appropriately for the weather since check-in is outdoors.
• Wait time and check-in time can be anywhere from 15 minutes to one hour, so please allow for that in your schedule. You will be given an estimated pick-up time for later that same day when you drop off your pet.
• Cats must be in carriers or other secure containers. Please leave your cat(s) in your vehicle during check-in. You can bring up to four cats per household. Separate carriers for each cat are preferable and should include a familiar towel or blanket.
• Dogs must come on a leash. No exceptions are permitted. There is a limit of three dogs per household.
• Most days we are able to help multiple animals from the same household. However, on busier days, you may be asked to return another time to have your additional pets’ surgeries performed. We try to accommodate as many patrons as we can. Trap-neuter-return (TNR) cats will take priority during check-in, and will be spayed/neutered as soon as possible. Although we make efforts to schedule TNR cats in advance with colony caretakers, sometimes their arrival is difficult to predict due to the challenges of trapping community cats. We appreciate your patience as we assist colony caretakers in spaying/neutering unowned cats.
• Although it is not required, you are urged to have your pets seen by a veterinarian in advance of the clinic to rule out any health problems that would make surgery unadvisable. We do not perform extensive pre-surgical examinations or blood analysis. If your pet has any medical issues (such as kidney, liver or heart problems) or is older than 7 years, there are increased risks associated with any operation. Please note that if for any reason we determine that spay/neuter surgery at our clinic would not be appropriate, we will not accept your pet for the procedure. You will be urged to see your own veterinarian.
• Generally speaking, post-surgery veterinary care is not necessary. However, if a problem occurs that requires medical attention, patrons of the Meow Mobile are advised to take their cats to Broadview Animal Hospital in Aurora. Denver-area patrons of the Lulu Mobile take their dogs or cats to the Dumb Friends League Quebec Street shelter. Patrons who attend a clinic outside of metro Denver can take their animals to a local veterinarian with whom we have made prior arrangements. Appointments are required. Post-surgery home-care instructions include the appropriate telephone numbers.
• Fees are $10 per cat and $50 per dog. We accept cash, check or charge for payment. Donations greatly appreciated.
• Please make sure someone will be at home with your pet for the rest of the day following surgery.
