Non-native predators: Murder mittens of domesticated cats not funny to outdoor wildlife

Cats are among the world’s most cherished companions, but when allowed to roam freely outdoors, they are non-native predators who become a deadly threat to native wildlife.

The Wildlife Center of Virginia calls on all cat owners to take a simple yet powerful step to protect wildlife and their pets: keep cats safely indoors.

Each year, the Center admits thousands of wild animals who suffer from injuries, many of which are caused by free-roaming domestic cats. In 2025 alone, the Center has already admitted 202 animals attacked by cats. Unfortunately, most of the patients did not survive. Cat-related injuries are often far more serious than they appear. Even minor bites or scratches from cats can introduce bacteria that are fatal to small mammals, birds and reptiles.

“Even with skilled veterinary care, the odds of survival are low. And the reality is, we only see a small fraction of the damage. Most animals caught by cats are killed and never make it to us,” Wildlife Center of Virginia’s Director of Veterinary Services Dr. Karra Pierce said.

A landmark 11-year study published in The Journal of Wildlife Management in 2016 underscores the scope of the issue. Drawing on patient records from the Wildlife Center from 2000 to 2010, researchers found that 14 percent, or nearly 3,000 animals, were confirmed victims of cat attacks.

Outdoor cats also face serious risks themselves. Vehicles, predators, toxins, disease and severe weather all pose constant threats. Indoor cats, by contrast, live significantly longer and healthier lives.

“We’re not anti-cat—many of us, myself included, are devoted cat owners. But we can’t ignore the significant impact cats have on wildlife. Keeping cats indoors protects native species and keeps our pets safe. It’s truly a win-win,” Pierce said.

Cat parents are encouraged to:
Keep your cat indoors, or supervise outdoor time with a harness or in a secure “catio.”
Prevent accidental escapes by ensuring screens and doors are secure.
