No. Cats are not legally allowed to roam freely in Denver. The city has no specific “cat leash law,” but all pets must be under control outdoors. The Denver Housing Authority requires cats to be leashed or contained when outside residential units for safety and compliance.
What do Denver’s pet laws say about cats?
Denver does not have a cat leash law. However, the city recommends keeping cats indoors or supervised outside. Uncontrolled roaming can lead to harm, nuisance complaints, or wildlife danger. Denver Animal Protection (DAP) suggests cats stay on private property for safety.
Are there leash laws for dogs in Denver?
Yes. Dogs must be on a leash in all public areas. According to Denver Revised Municipal Code §8-16, dogs cannot roam freely. Owners must maintain physical control at all times in parks, streets, and shared spaces.
Why are cats allowed to roam but not dogs?
Cats are semi-feral and harder to regulate. Denver animal control focuses enforcement on dogs due to public safety risks. Cats are less likely to attack or cause traffic incidents, but roaming is still discouraged.
What are the risks of letting cats roam freely?
Outdoor cats face injury, disease, and wildlife threats. According to the American Veterinary Medical Association (AVMA), outdoor cats live only 2–5 years, compared to 10–15 years for indoor cats. Risks include traffic, predators, poisoning, and infections such as feline leukemia.
What does the Denver Housing Authority require for pets?
Pets must be on a leash or under control outdoors. The Denver Housing Authority (DHA) pet policy states that cats and dogs must be leashed or carried when outside a dwelling unit. Unleashed animals can result in tenant violations or fines.
What happens if animal control finds a loose cat?
Sick, injured, or biting cats may be impounded. Healthy roaming cats are not always captured unless they create problems. Denver Animal Protection responds to complaints or safety concerns involving domestic or feral cats.
Are there cat-specific safety options like catios?
Yes. Catios help keep cats safe and contained. A catio is an enclosed outdoor structure that allows fresh air and sun without risk. Many Denver residents build catios to follow containment advice while enriching pet life.
Is it illegal to abandon a cat in Denver?
Yes. Abandoning any pet is illegal in Colorado. Under Colorado Revised Statute §18-9-202, animal abandonment or neglect counts as cruelty. Offenders face fines or criminal charges.
What can residents do about stray or nuisance cats?
Contact Denver Animal Protection (DAP). The agency helps with humane trapping and rescue. Residents may also contact local shelters for spay-neuter programs or feral cat care guidance.

People Also Ask
Is There a Leash Law in Denver?
Yes. There is a leash law for dogs in Denver, but cats are not required to be on a leash.
According to the Denver Municipal Code, dogs are not permitted to “run at large.” They must be on a leash, cord, or chain when outside the owner’s property. This rule applies to all public areas, including parks, streets, and sidewalks, unless the location is a designated off-leash area.
The purpose of this law is to protect public safety and prevent harm to other animals. While dogs must always be restrained, most local ordinances—including Denver’s—do not have leash requirements for cats.
What Is the New Law About Pets in Colorado?
Recent Colorado legislation has focused on strengthening pet protections, especially in housing and sales.
A major new law effective January 1, 2024, limits pet-related costs in rental housing:
Pet rent is capped at $35 per month or 1.5% of monthly rent, whichever is greater.
Pet security deposits are capped at $300, and must be refundable.
This law helps make housing more accessible and affordable for pet owners.
Additionally, starting August 6, 2025, it will be illegal to sell, offer for adoption, or transfer any pet animal in public spaces such as roadsides, parking lots, or parks. This measure targets unregulated pet sales often linked to large-scale commercial breeding operations.
What Are the Animal Laws in Colorado?
Colorado’s animal laws combine state statutes and local ordinances governing licensing, cruelty, and containment.
Key requirements include:
Licensing: Dogs and cats over six months old must be licensed.
Vaccination: A current rabies vaccination is mandatory for both dogs and cats.
Local rules: Some cities require spaying or neutering.
Colorado prohibits animal cruelty, which includes mistreating, neglecting, or abandoning an animal.
Cruelty can be charged as a misdemeanor or felony, with fines or jail time.
Aggravated cruelty—intentional torture or killing—is a felony offense.
Leash laws for dogs are set by municipalities. Denver enforces a strict leash law in all public areas.
Why Are Cats Allowed to Roam Free but Not Dogs?
The difference stems from behavior, safety, and enforcement challenges.
Dogs pose greater public safety risks—they can form packs, chase vehicles, or behave aggressively. Cats, however, are independent and solitary. While they may disturb neighbors or harm wildlife, they rarely threaten people directly.
Culturally, cats have long been allowed to roam, and enforcing leash laws for cats is impractical. Cities like Denver focus enforcement resources on dogs, where the public safety risk is higher.
Is It Illegal to Abandon a Cat in Denver?
Yes. Abandoning a cat in Denver is illegal and classified as animal cruelty under Colorado law.
The Colorado cruelty statute defines abandonment as leaving an animal without proper care or provisions. In Denver:
Leaving a pet alone for over 72 hours at a private residence, or
Leaving a pet for over one hour in a public place
…is considered abandonment.
Pet owners unable to provide care must surrender their animals to a licensed shelter, such as the Denver Animal Shelter. This ensures safety, legality, and humane treatment.
