Can Cats Contract Lyme Disease by Eating Infected Mice?

Yes, cats can get Lyme disease from eating mice. Here is why and how it happens.

Ticks are known carriers of Lyme disease, and when mice get bitten by ticks, they can contract the disease. Since cats are natural predators and may catch and consume mice, there is a chance they can become infected with Lyme disease.

It is important to be aware of this risk and take measures to keep your cats protected. In the following paragraphs, we will discuss the transmission of Lyme disease, symptoms to watch out for, and preventive measures to safeguard your feline companion. Stay informed to ensure the health and well-being of your furry friend.

The Connection Between Lyme Disease And Mice

It is important to understand the role of mice in transmitting Lyme disease to cats. Lyme disease is primarily transmitted through ticks, but mice play a significant role in the life cycle of these ticks. The bacteria that cause Lyme disease, called Borrelia burgdorferi, can be present in the bloodstream of mice that are infected with ticks carrying the bacteria.

When ticks feed on infected mice, they become carriers of the bacteria. Subsequently, when these infected ticks bite cats, they can transmit the bacteria, potentially leading to Lyme disease in feline companions. While cats are generally less susceptible to Lyme disease compared to dogs and humans, it is still essential to be cautious.

To minimize the risk of cats contracting Lyme disease, it is important to keep them protected from tick bites. This can be achieved through regular tick checks, using tick preventatives recommended by veterinarians, and ensuring a tick-free environment by keeping the yard clean and avoiding areas with high tick populations. By taking these precautions, we can help protect our furry friends from the threat of Lyme disease.

Symptoms Of Lyme Disease In Cats

  • Lameness: One of the most common signs of Lyme disease in cats is lameness or limping. Cats may have difficulty walking or exhibit stiffness in their legs.
  • Loss of appetite: Lyme disease can cause cats to lose their appetite. If your cat is refusing to eat or showing a decrease in food consumption, it could be a sign of the disease.
  • Lethargy: Cats infected with Lyme disease often become lethargic and lack energy. They may seem tired or uninterested in their usual activities.
  • Fever: A persistent fever is another symptom to watch for. If your cat has an elevated body temperature that lasts for several days or more, it could be a sign of Lyme disease.
  • Swollen joints: Some cats with Lyme disease may develop swollen joints, particularly in their limbs. This can cause discomfort and difficulty in movement.
  • Decreased grooming: Cats are known for their grooming habits, so if you notice a decrease in grooming behavior, it may be an indication of Lyme disease.

If you observe any of these symptoms in your cat, it is important to consult with a veterinarian for proper diagnosis and treatment. Early detection can prevent the progression of Lyme disease and improve your cat’s overall health.

Transmission Of Lyme Disease From Mice To Cats

Transmission of Lyme Disease from mice to cats can occur through ticks. Ticks are the main vectors responsible for spreading the disease. When ticks attach themselves to mice, they can become carriers of the Lyme disease bacteria, Borrelia burgdorferi. As mice are highly susceptible to infection, they can harbor a significant number of infected ticks.

If a cat comes into contact with an infected mouse, the ticks can easily transfer the Lyme disease bacteria to the cat. Cats are also at risk of exposure to infected ticks directly.

It’s important to understand that while mice can be potential carriers of Lyme disease, they are not direct sources of transmission. Ticks play a crucial role in transmitting the bacteria from mice to cats and other animals. Therefore, taking preventative measures to protect both cats and mice from tick bites can help minimize the risk of Lyme disease transmission.

Diagnosis And Testing For Lyme Disease In Cats

Diagnosing Lyme disease in cats is crucial for their overall health and well-being. Early detection plays a vital role in ensuring effective treatment. Veterinarians employ various methods to test for Lyme disease in cats.

One common diagnostic test is a blood test that looks for the presence of antibodies against the bacteria responsible for Lyme disease. The two most commonly used blood tests are the C6 antibody test and the Quantitative C6 antibody test. These tests can detect antibodies produced by the cat’s immune system in response to the bacteria.

Another method used for diagnosing Lyme disease in cats is polymerase chain reaction (PCR) testing. This test detects the genetic material of the bacteria in the cat’s blood and can provide a direct confirmation of infection.

Additionally, veterinarians may utilize the SNAP 4Dx Plus Test, which can detect Lyme disease as well as other tick-borne diseases in cats. This comprehensive test can be helpful in determining the overall tick exposure of the cat.

It is important to note that a positive test result does not always indicate that the cat is actively infected or experiencing clinical symptoms. Additional clinical signs and the cat’s medical history should be considered when interpreting the test results.

In conclusion, early diagnosis and testing are crucial for detecting Lyme disease in cats. Veterinarians can utilize various tests, such as blood tests and PCR testing, to confirm the presence of the bacteria. The SNAP 4Dx Plus Test can provide a comprehensive evaluation of tick-borne diseases in cats. Early detection allows for timely treatment and improved outcomes for our feline friends.

Treatment Options For Cats With Lyme Disease

Lyme disease in cats is primarily transmitted through tick bites, but can cats get it from eating mice? The short answer is no. The bacteria responsible for causing Lyme disease, Borrelia burgdorferi, is not present in mice. However, it is still important to be aware of recommended treatments for cats with Lyme disease.

Recommended Treatments For Cats With Lyme Disease:

Treatment Description
Medications Veterinarians may prescribe antibiotics, such as doxycycline or amoxicillin, to eliminate the bacteria causing Lyme disease.
Therapies In addition to medications, supportive therapies such as pain management and inflammation control may be recommended to alleviate symptoms.

It is important to consult with a veterinarian for specific treatment recommendations tailored to your cat’s condition. Managing Lyme disease in cats involves a comprehensive approach that includes medications, therapies, and strategies. With proper care, cats can recover from Lyme disease and lead healthy lives.

Prevention And Protection For Cats

  • Keep cats indoors during peak tick season, typically spring and summer, to minimize exposure.
  • Regularly inspect your cat for ticks after outdoor activities and remove any found ticks immediately.
  • Use tick prevention products recommended by veterinarians, such as topical treatments or oral medications.
  • Create a tick-free zone in your yard by regularly mowing the grass, removing leaf litter, and keeping shrubs trimmed.
  • Prevent access to mice by sealing any cracks or holes in your home.
  • Keep your cat’s food securely stored to deter mice and reduce the chance of them entering your home.
  • Consider using mouse traps or professional pest control services to eliminate existing mice infestations.
  • Consult with your veterinarian about vaccinating your cat against Lyme disease to provide additional protection.

By following these preventive measures, you can significantly reduce the risk of your cat contracting Lyme disease from eating mice.


To summarize, while cats can contract Lyme disease from mice, it is relatively rare. However, it is still important to take preventative measures such as keeping your cat indoors and using tick prevention methods. Additionally, regular check-ups with your veterinarian can help catch any potential illnesses early on.

By being proactive, you can help ensure your cat’s health and minimize the risk of Lyme disease.
