Do Bed Bugs Feed on Cats? Exploring the Unlikely Connection Between Bed Bugs and Feline Diets

When it comes to the question, “Do bed bugs feed on cats?” the answer is both straightforward and complex. Bed bugs, scientifically known as Cimex lectularius, are parasitic insects that primarily feed on human blood. However, their feeding habits are not exclusive to humans. While bed bugs prefer human hosts, they are opportunistic feeders and can bite other warm-blooded animals, including cats, dogs, and even birds. But does this mean bed bugs actively seek out cats as a food source? Let’s dive deeper into this intriguing topic.

The Feeding Habits of Bed Bugs

Bed bugs are nocturnal creatures that thrive in environments where they can easily access their preferred host: humans. They are attracted to the carbon dioxide we exhale, body heat, and certain chemicals in our sweat. While they are not known to transmit diseases, their bites can cause itching, allergic reactions, and psychological distress.

Cats, on the other hand, are not typically a bed bug’s first choice. Bed bugs are more likely to infest areas where humans sleep or rest, such as beds, couches, and chairs. Cats, being smaller and less predictable in their movements, are less likely to provide a consistent food source for bed bugs. However, in cases of severe infestations or when human hosts are unavailable, bed bugs may resort to feeding on cats.

Can Bed Bugs Survive on Cats Alone?

While bed bugs can bite cats, they cannot survive solely on feline blood. Bed bugs require regular access to a host to complete their life cycle, and human blood provides the necessary nutrients for their development. Cats, being smaller and less accessible, do not offer the same level of sustenance. Additionally, cats groom themselves frequently, which can make it difficult for bed bugs to remain attached long enough to feed.

The Impact of Bed Bugs on Cats

If bed bugs do bite a cat, the effects are usually minimal. Cats may experience mild itching or irritation at the bite site, but serious health issues are rare. However, in rare cases, a cat may develop an allergic reaction to bed bug bites, leading to more severe symptoms such as swelling, redness, or even hair loss. It’s also worth noting that cats can inadvertently transport bed bugs from one location to another, especially if they spend time in infested areas.

Preventing Bed Bugs from Affecting Your Cat

To protect your cat from bed bugs, it’s essential to address the root cause: the bed bug infestation itself. Here are some steps you can take:

  1. Inspect Your Home Regularly: Check for signs of bed bugs, such as tiny blood stains on sheets, dark fecal spots, or shed exoskeletons.
  2. Wash Bedding and Fabrics: Regularly wash your cat’s bedding, as well as your own, in hot water to kill any bed bugs or eggs.
  3. Vacuum Frequently: Vacuum carpets, furniture, and other areas where bed bugs may hide. Be sure to dispose of the vacuum bag or contents immediately.
  4. Use Protective Covers: Encase mattresses and pillows in bed bug-proof covers to prevent infestations.
  5. Consult a Professional: If you suspect a bed bug infestation, contact a pest control expert to assess and treat your home.

The Unlikely Connection: Bed Bugs and Feline Diets

While bed bugs and cats may seem like an odd pairing, their interaction raises interesting questions about the adaptability of parasites. Bed bugs, despite their preference for human blood, demonstrate a remarkable ability to survive in diverse environments. Cats, as natural predators, may inadvertently help control other pests but are unlikely to play a significant role in managing bed bug populations.

In conclusion, while bed bugs can and do bite cats, they are not a primary food source for these pests. The relationship between bed bugs and cats is more about proximity and opportunity than a deliberate choice. By maintaining a clean and vigilant home environment, you can minimize the risk of bed bugs affecting both you and your feline companion.


Q: Can bed bugs live on cats?
A: No, bed bugs cannot live on cats. They may bite cats occasionally, but they do not reside on their bodies like fleas or ticks.

Q: How can I tell if my cat has been bitten by bed bugs?
A: Look for small, red, itchy bumps on your cat’s skin, particularly in areas with less fur. However, these symptoms can also be caused by other pests, so it’s best to consult a veterinarian for a proper diagnosis.

Q: Are bed bugs dangerous to cats?
A: Bed bugs are generally not dangerous to cats. While their bites can cause mild irritation, they do not transmit diseases to felines.

Q: Can cats help get rid of bed bugs?
A: Cats are not effective at controlling bed bug infestations. Professional pest control methods are necessary to eliminate bed bugs completely.

Q: Do bed bugs prefer humans over cats?
A: Yes, bed bugs prefer human blood over that of cats or other animals. They are more likely to infest areas where humans sleep or rest.
