The Potter League for Animals, founded in 1929, is one of Rhode Island's oldest and most complete animal welfare organizations. From its Middletown center it runs adoption, a subsidized spay and neuter clinic in Warwick, and animal-control sheltering for the Aquidneck Island towns. Here is how adoption, surrender, and its services work, with current fees.
The Potter League describes itself as an open-admission shelter rather than a no-kill one, explaining that it never has to euthanize an animal for lack of space and gives no adoptable animal a time limit. Every adoptable pet, it says, finds a home regardless of how long it takes.
It is also the animal-control sheltering hub for Aquidneck Island, serving as the housing facility for the Newport, Middletown, and Portsmouth animal-control departments. Owned animals are accepted from across Rhode Island, with priority for Newport County residents, while strays come from the contracted island towns.
Adoption fees are published, with a 10 percent discount for active and veteran military and for seniors 65 and older. Each adoption includes spay or neuter surgery, age-appropriate vaccines, a microchip and ID tag, flea and tick prevention, a certificate for a veterinary exam within 14 days, medical records, and a food sample; dogs add a one-month crate rental and a training class discount, and cats add a collar and carrier.
| Animal | Adoption fee |
|---|---|
| Dog | $325 |
| Puppy, 6 months and under | $450 |
| Cat | $150 |
| Kitten, 6 months and under | $250 |
| Rabbit | $50 |
| Other small animals | $20 to $65 |
Adoption is in person and first-come, first-served, with no holds; clicking adopt online does not reserve an animal. You browse pets, then visit the Middletown center to meet an adoption counselor and finish the adoption that day. The center is open every day, 10 a.m. to 5 p.m.
The Potter League spay and neuter clinic in Warwick provides subsidized surgery for Rhode Island cats and dogs and performs more than 6,000 surgeries a year. The organization also holds discounted or free vaccine clinics through the year. Its standalone low-cost public veterinary clinic in Riverside closed in 2025 and reopened under a separate nonprofit, so it is no longer a Potter League facility.
Owner surrender is by appointment after a personality-profile review. Fees are $50 for a dog or puppy, $35 for a cat or kitten, $50 for a litter of three or more kittens, $25 for a rabbit, and $10 for other small animals, with no fee for strays, and no animal is turned away for financial hardship. Newport County residents get priority.
The Potter League also runs a pet food pantry, humane education programs, a behavior helpline, and pet cremation services.
Volunteers can help independently from age 15, and younger children 10 and up can take part with adult supervision. Fostering is for adults 18 and older who live within 40 miles of the shelter and have their own transportation; the Potter League provides food, litter, supplies, and all medical care, and cannot place foster animals in Massachusetts homes.
The wish list includes bully sticks and puzzle toys, Timothy hay, disinfecting wipes, and food-pantry staples, with Amazon and Chewy lists available. The Potter League holds a four-star rating from Charity Navigator with a 90 percent score, ranking in the top tier of animal welfare organizations nationally. Its EIN is 05-0301553.
