Why Do Cats Kill Birds And Not Eat Them?

Cats are efficient hunters with deadly predatory instincts. If you’ve ever had an outdoor cat, you’ve likely experienced the unpleasant surprise of finding bird carcasses on your doorstep. So why do cats kill birds if they have no intention of eating them?

This common feline behavior has its roots in natural instincts and can be perplexing and frustrating for cat owners.

If you’re short on time, here’s the quick answer: Cats kill birds even when not hungry due to their strong hunting instincts and desire to hone their skills. It’s in their nature as predatory animals.

Cats Have a Strong Hunting Drive

Cats are natural-born hunters, and their hunting drive is deeply ingrained in their instincts. This is why they often display behaviors such as pouncing, stalking, and chasing. Even well-fed domestic cats still have a strong desire to hunt, which can lead to them killing birds without any intention of eating them.

Instinct to Hunt

Cats have been hunters for thousands of years, and their predatory instincts have been passed down through generations. Their keen senses, sharp claws, and agile bodies make them excellent hunters. When a cat sees a bird, their instincts kick in, triggering the chase and pounce response.

Opportunistic Killers

Cats are opportunistic predators, meaning they will hunt and kill whenever the opportunity arises, even if they are not hungry. They don’t differentiate between prey they need for sustenance and prey they don’t.

This is why cats may kill birds and leave them untouched, as they were simply taking advantage of an available target.

Play and Practice

Another reason why cats kill birds without eating them is for play and practice. Hunting is a form of exercise and mental stimulation for cats. By chasing and capturing birds, they are honing their hunting skills and satisfying their natural instincts.

Even though they may not consume the prey, the act of hunting itself is rewarding for them.

It’s worth noting that while cats are natural hunters, it’s important for cat owners to take measures to protect wildlife and encourage responsible behavior. Keeping cats indoors or in enclosed outdoor spaces can help reduce their impact on bird populations.

Additionally, providing cats with toys and interactive play can help satisfy their hunting instincts in a more controlled and eco-friendly way.

Not Hungry, Just Bored

One of the main reasons why cats kill birds but don’t eat them is simply because they are not hungry. Cats are natural predators, and hunting is an instinctual behavior for them. Even well-fed domesticated cats still retain this hunting instinct and may engage in hunting activities even when their nutritional needs are met.

Outdoor Access

Cats that have access to the outdoors are more likely to come across birds and other small animals. When they spot a bird, their natural hunting instincts kick in, and they may chase and capture it. However, once they catch the bird, they may lose interest in it because they were not motivated by hunger in the first place.

Lack of Stimulation

Indoor cats, on the other hand, may exhibit this behavior due to a lack of stimulation and opportunities for natural hunting. Without access to the outdoors or interactive toys, indoor cats may become bored and seek out alternative ways to entertain themselves.

Hunting birds, even if they don’t eat them, can provide a form of mental and physical stimulation for these cats.


Another reason why cats kill birds but don’t eat them is for recreational purposes. Cats are known for their playful nature, and hunting can be seen as a form of entertainment for them. Chasing and capturing a bird can be a thrilling activity for a cat, and once they have achieved their goal, the bird may no longer hold their interest.

It’s important to note that while cats killing birds is a natural behavior, it can have negative consequences for bird populations, especially for indigenous species. If you have an outdoor cat, consider providing them with alternative forms of stimulation and play, such as puzzle toys or interactive play sessions, to satisfy their hunting instincts without posing a threat to local wildlife.

How to Stop the Behavior

If you want to prevent your cat from killing birds, there are several steps you can take to discourage this behavior. These include keeping your cat indoors, providing enrichment, and using deterrents.

Keep Cats Indoors

One of the most effective ways to prevent cats from killing birds is to keep them indoors. By keeping your cat inside, you are not only protecting birds but also keeping your cat safe from potential dangers such as traffic, predators, and diseases.

Indoor cats can still have a happy and fulfilling life with plenty of stimulation and playtime.

According to the American Bird Conservancy, outdoor cats kill an estimated 2.4 billion birds each year in the United States alone. By keeping your cat indoors, you are helping to reduce the impact on bird populations.

Provide Enrichment

Cats are natural hunters, and they need an outlet for their hunting instincts. By providing enrichment for your cat, such as interactive toys, puzzle feeders, and engaging playtime, you can help satisfy their hunting needs. This can help reduce the desire to hunt birds and other wildlife.

Enrichment can also include creating vertical spaces for your cat to climb, hiding spots, and scratching posts. These environmental enhancements can provide mental and physical stimulation, preventing boredom and the need to seek out prey.

Use Deterrents

If you have a cat that has a strong hunting instinct, you can use deterrents to discourage them from hunting birds. One option is to use a bird feeder that is designed to keep cats out. These feeders are typically elevated or have barriers that prevent cats from accessing the birds.

Another option is to use deterrents in your yard that make it less attractive to birds, such as motion-activated sprinklers or decoy predators. These can help create a less appealing hunting environment for your cat.

It’s important to remember that cats are natural predators, and their hunting instincts can be difficult to completely eliminate. However, by taking these steps, you can help reduce the likelihood of your cat killing birds and protect both wildlife and your beloved feline friend.


In the end, cats kill birds even when not hungry because hunting is deeply ingrained in their instincts and nature as predators. Though frustrating, this common behavior is a reflection of their wild origins.

With proper care and management, cat owners can curb the instinct and prevent needless bird deaths.
