Do Cats Eat Roaches?

Cats, known for their natural hunting instincts, often find themselves in pursuit of various prey, including insects like cockroaches. With their excellent predatory skills, cats tend to stalk, catch, and play with roaches that cross their paths. This behavior leads many to wonder whether cats actually consume these resilient insects and if doing so may pose any risks to their health.

While it is true that some cats will eat cockroaches if given the opportunity, the primary reason for this behavior is not to fulfill a dietary need for protein. Instead, cats are driven to hunt cockroaches due to their innate predatory instincts. However, concerns arise when considering the potential harm that ingesting roaches may cause, as these insects can carry bacteria, viruses, and parasites from crawling across decaying or rotten substances.

Ensuring that cats are fed a balanced and complete diet is essential in minimizing their need to hunt for additional food sources. While hunting cockroaches may not be completely avoidable, understanding the risks associated with such actions can help cat owners make informed decisions about their pets’ well-being.

Cats and Their Hunting Behavior

Understanding Cat’s Hunting Instincts

Cats, both domestic and feral, possess natural hunting instincts that have been inherited from their wild ancestors. Their predatory behavior can be traced back to the time when they relied on hunting for survival. Even though domestic cats receive regular meals, they still exhibit hunting behaviors due to these innate instincts. Chasing, stalking, and pouncing are common actions observed in cats, regardless of whether they live indoors or outdoors.

Cats are known for their agility, speed, and sharp senses, which makes them efficient hunters. Their vision is adapted to detect even the slightest movements, allowing them to spot potential prey easily. Their whiskers also serve as sensors for detecting changes in air currents and vibrations, further assisting them in their hunting pursuits.

Different Preys Hunted by Cats

Cats can hunt a diverse range of prey types, from insects to small mammals. In the wild, feral cats will often hunt for food, relying mainly on their skills to catch various creatures. Some of the common prey items for feral cats include mice, birds, and small mammals. Domestic cats, on the other hand, might occasionally engage in stalking and chasing neighborhood critters or insects, even if they are well-fed.

Cats, as natural-born predators, are attracted to the quick, scuttling movements of insects, such as cockroaches. This stimulation of their hunting instincts can lead them to catch and sometimes eat these insects. However, hunting for insects is more often a result of their predatory behavior rather than a dietary need.

Lions, as part of the cat family, also share similar hunting instincts. They predominantly hunt large mammals like antelopes, zebras, and wildebeest in the wild, showcasing their impressive strength and hunting abilities.

While hunted insects like cockroaches might provide small amounts of protein and nutrients, it’s not essential for a cat’s diet, especially when proper cat food is provided. Owners should always provide well-balanced meals to satisfy their cat’s dietary needs and discourage hunting insects for nourishment. However, it’s important to understand that a certain level of hunting behavior is an inescapable part of a cat’s nature.

Cockroaches as Potential Cat Prey

Cats, being natural hunters, might find cockroaches interesting due to their scampering movements and size. They usually prey on smaller mammals, birds, reptiles, amphibians, and invertebrates like crickets and grasshoppers as well. In this section, we will discuss the pros and cons of cats eating roaches and the health impact it might have on them.

Pros and Cons of Eating Roaches

Cockroaches could provide some nutrients for cats, as they contain proteins and amino acids just like other invertebrates. However, cats do not primarily hunt cockroaches for their nutritional content.


  1. Entertainment: Hunting cockroaches can keep cats occupied and engage their natural predatory instincts.
  2. Nutrients: Cockroaches might offer a small amount of nutrition as they contain protein and amino acids.


  1. Pesticides: Cockroaches might have been exposed to pesticides, which could be poisonous if ingested by a cat.
  2. Parasites: Roaches may carry parasites or disease, which could pose a risk to a cat’s health.
  3. Indigestion: Due to the exoskeleton of roaches, they might be difficult for cats to digest and could cause indigestion or blockages.

The Health Impact on Cats

Cats might suffer some health issues due to the ingestion of roaches. The exoskeleton of cockroaches is made of chitin, a material that can be difficult for cats to digest, potentially leading to indigestion or gastrointestinal blockages.

In addition, consuming roaches that have come into contact with pesticides or other chemicals could cause poisoning, especially if the cat eats a large number of roaches from an infested area. Roaches are also known to carry various microbes and parasites which may lead to infections or other health issues in cats.

Due to these risks, it is generally preferable for cat owners to address roach infestations using other methods, such as trapping, sealing off entry points, and maintaining a clean environment, rather than relying on their cats to catch and eat cockroaches.

Health Risks for Cats Consuming Roaches

Potential Diseases and Symptoms

Cats eating roaches can be exposed to various health risks. Roaches may carry bacteria, viruses, and parasites that pose a threat to a cat’s health. Some of the common diseases that can be transmitted by roaches include Salmonella, E. coli, and hookworms. Symptoms associated with these diseases can range from mild to severe, affecting several body systems.

Here’s a list of some common symptoms which may be experienced by cats after ingesting infected roaches:

  • Digestive system: Diarrhea, vomiting, and gastroenteritis.
  • Nervous system: Disorientation, lethargy, seizures, and lack of coordination.
  • Respiratory system: Breathing difficulties and oral irritation.

It is essential to keep an eye on your cat’s health and consult your veterinarian if any unusual symptoms appear.

Prevention Tips and Recommendations

To minimize the risk of your cat consuming roaches, consider the following preventive measures:

  1. Pest control: Regularly inspect your home for any signs of roach infestation. Take appropriate steps to eliminate roaches using safe and non-toxic methods.
  2. Cat safe environments: Keep your cat indoors or provide a secure outdoor space where they are less likely to encounter pests.
  3. Know your cat’s habits: If your cat is prone to consuming insects, exercise caution and discourage this behavior.
  4. Toxic substances: Ensure that roaches have not been exposed to poison or other toxic substances before allowing your cat to interact with them.
  5. Consult with your veterinarian: Seek advice from a professional regarding your cat’s health and any potential risks associated with their diet and environment.

By implementing these preventive steps, you can protect your cat from the potential health risks associated with consuming roaches. Always monitor your cat’s behavior and consult your veterinarian if you suspect any health problems related to their interaction with insects.
