On our mobile spay/neuter clinics, we reach out in a spirit of compassion to pet owners in underserved areas by providing high-quality, affordable spay/neuter surgeries to their cats and dogs.

Pet owners in underserved areas can get spay/neuter services for their pets at reduced fees, subsidized by Dumb Friends League donors, through our mobile spay/neuter clinics.

The Meow Mobile offers spay/neuter services for cats, and the Lulu Mobile offers spay/neuter services for dogs. We do not provide services to animals who are not undergoing spay/neuter services.

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.

Both clinics are staffed with veterinarians who are licensed in the state of Colorado.
