Caring for feral cats from sunrise to sunset.

Compassionate, volunteer-run care for Sunnyside cats.

About us

Feral Friends of Sunnyside is a group of five local volunteers committed to improving the lives of community (feral) cats who live outdoors in our Denver, CO neighborhood.

Cats are not a native species and cannot live independently without human intervention. Without consistent care, outdoor cats face hunger, illness, injury, and unchecked population growth. While feral cats live very different lives than domestic cats, thoughtful, ongoing care makes a meaningful difference.

 

We provide daily food, water, and shelter, coordinate humane Trap-Neuter-Return (TNR), and raise funds for necessary veterinary care such as spay/neuter surgeries, dental procedures, and treatment for painful conditions like severe matting.

Our goal is simple: reduce suffering, stabilize the population, and support the best possible quality of life for cats who depend on us.

What we do

Every day, from early morning feedings to evening check-ins, we show up for cats who depend on consistent human care to survive.

  • DAILY CARE
    We maintain feeding stations throughout Sunnyside, ensuring cats have reliable access to nutritious food, clean water, and weather-appropriate shelter for every season.
    Daily care helps reduce illness, stress, and risky behavior caused by hunger or exposure.
  • TRAP-NEUTER-RETURN (TNR)
    When possible, we use humane TNR practices to:
    • Spay or neuter feral cats
    • Vaccinate against common diseases
    • Return cats safely to their established outdoor homes
    TNR is the most effective, evidence-based approach to reducing feral cat populations while improving overall colony health.
  • MEDICAL CARE
    When cats require additional support, we fundraise to cover essential veterinary expenses, including:
    • Spay and neuter surgeries
    • Dental cleanings and extractions
    • Dematting and treatment for painful coat conditions
    These interventions significantly improve comfort and long-term health.
  • ADOPTION SUPPORT
    Some cats show signs of socialization and are eligible for placement in shelter programs. When that happens, we work with partner organizations to support further socialization and adoption.

Meet the cats

Each cat we care for has their own personality, history, and comfort level with humans. While most are not adoptable, all benefit from consistent care and humane management.

  • Tortoiseshell longhair cat

    Taffy

    Tortoiseshell longhair

    Taffy comes running when you call her name and is known for being talkative and sweet—while still keeping a respectful distance. She's had visitors over the years, including a friendly cat named Salty, who was successfully socialized, adopted, and now lives at an office nearby. Taffy remains a neighborhood favorite, always happy to greet volunteers on her terms.

  • Gray shorthair cat

    Gray Boy

    Gray shorthair

    Small but mighty, Gray Boy is full of spirit and enthusiasm. He runs up to the car at feeding time and eagerly reaches for his bowls—sometimes showing off his claws in the process. Volunteers use creative tools like grabbers to keep everyone safe, understanding that his behavior comes from excitement, not aggression. A true junkyard cat, Gray Boy isn't shy about saying hello. He's also had many visitors over the years, including Butter Scotch and several kittens who were trapped, neutered, and either returned or adopted when eligible.

  • Black shorthair cat

    Lily

    Black shorthair

    Lily is no longer part of the feeding route, but she remains one of our favorite success stories. She showed enough social behavior to be safely trapped and transferred to a shelter, where she was further socialized and eventually adopted into a home. We love a success story.

  • Golden longhair & black shorthair cat

    Goldie & Junior

    Golden longhair & black shorthair

    This bonded pair lives in a nearby warehouse lot. They'll come when called, but prefer to keep their distance—often hiding behind cars until they feel safe. Goldie usually leads the way, with Junior close behind.

  • Tortoiseshell shorthair & black shorthair cat

    Ms. Tortie & Blackie

    Tortoiseshell shorthair & black shorthair

    These littermates stay close together. Ms. Tortie is outspoken and doesn't shy away from letting you know when she's hungry, slipping through a hole in the fence to demand that dinner be served promptly before retreating back behind the fence with Blackie to wait for food.

  • Gray longhair & tuxedo shorthair cat

    Ghost & Fancy Pants

    Gray longhair & tuxedo shorthair

    These two boys are beauties through and through. Fancy Pants, a striking black tuxedo, has grown comfortable at feeding time and is often found lounging proudly on top of his shelter. Ghost lives up to his name—skittish and elusive—but reliably appears when he feels safe enough to eat.
