Authorities in Northglenn, a suburb north of Denver, have removed more than 100 animals from a residential property in what officials are calling a significant case of animal cruelty and neglect.

A search warrant was executed on July 16 at a home near Wyco Park, after local law enforcement received reports of inhumane conditions. Officers arrived to find a staggering 117 animals — 96 cats and 19 dogs — crammed into a space described by police as “unsanitary” and “hazardous.”

Disturbing Discovery Inside the Home

Among the animals found, one cat and one dog were discovered dead. The remaining pets have since been transported to area shelters for medical assessments and temporary care.

Northglenn Police say the homeowner is facing criminal charges related to animal cruelty and neglect. Officials have not released the homeowner’s identity, but confirmed that the investigation remains active.

“These are tragic circumstances for the animals involved,” said a spokesperson for the department. “We’re thankful we were able to intervene when we did.”

Riverdale Animal Shelter Mobilizes Emergency Response

The Riverdale Animal Shelter, one of the region’s largest intake facilities, is spearheading the care of the rescued pets.

In a statement, the shelter said it is working around the clock to assess medical needs and stabilize conditions for the animals. Many of the cats and dogs were reportedly suffering from malnutrition, untreated illnesses, and stress from overcrowding.

Cheryl Martinez, a lead volunteer at Riverdale, called the rescue effort “one of the most demanding we’ve seen this year.”

“Our team is working nonstop. These animals deserve dignity and healing — that’s our priority,” Martinez said.

How the Community Can Help

As shelter staff deal with the influx, officials are asking the public for help — not just financially, but with supplies and time.

The Northglenn Police Department shared a list of immediate donation needs:

• Purina-brand food, especially kitten formulas

• Soft dog treats for animals with dental issues

• Towels (new or gently used) for bedding and cleaning

• Recyclables like cardboard boxes and toilet paper rolls for enrichment

• Newspapers for lining enclosures

In addition, the shelter is seeking foster families, volunteers, and adopters. Monetary donations can be made directly through the Riverdale Animal Shelter’s website.

Ongoing Investigation

Investigators are still collecting evidence and reviewing prior complaints related to the property. Community members with relevant information are urged to call the Northglenn Police Department at 303-450-8892.

As of Tuesday morning, several of the rescued animals were showing signs of improvement, though many still require veterinary care and socialization before becoming eligible for adoption.

Officials say it’s too early to determine how long rehabilitation will take — but the work, they stress, is already underway.
