What diseases can cats get from mice?

Have you ever watched your cat pounce on a mouse with impressive agility and thought, “What diseases can my furry friend catch from that little rodent?” Well, the truth is that mice are more than just pesky critters. They can also pose serious health risks to your beloved pet.

As natural hunters, cats love to chase and catch mice. But did you know that these tiny rodents can transmit deadly diseases to our feline friends? One of the most dangerous illnesses is Leptospirosis, a bacterial infection that can lead to liver and kidney failure. Another lethal disease is Hantavirus, which spreads through breathing in infected fecal dust from mice. Symptoms include fever, muscle aches, and fatigue and can even result in respiratory failure.

But it’s not just these two diseases that we need to worry about. Mice carry other harmful bacteria such as Salmonella and Listeria. And let’s not forget about the infamous bubonic plague. Cats who hunt and eat mice are at high risk of contracting these serious illnesses which can also be transmitted to humans.

That’s why it’s crucial to keep your home mouse-free and take preventive measures to protect your pet cat from catching any diseases. Trust us; you don’t want to deal with the consequences of a sick kitty or worse yet, one who passes on their illness to you.

Hantavirus Pulmonary Syndrome (HPS)

Hantavirus Pulmonary Syndrome (HPS) is a severe disease that can cause respiratory distress in both humans and animals. This virus is primarily found in wild rodents, such as deer mice, and can be transmitted to cats through contact with infected mice or their droppings.

If your cat has contracted HPS, they may exhibit symptoms such as fever, lethargy, coughing, and difficulty breathing. In severe cases, the virus can lead to respiratory failure and death. While it is rare for cats to contract HPS from mice, it is still important to take steps to prevent potential exposure.

To protect your furry friend from HPS, here are some essential tips:

  • Keep your cat indoors or closely monitor them while they are outside. This will reduce their exposure to infected rodents and their droppings.
  • Regularly clean and disinfect areas where rodents may be present, such as garages or barns.
  • If you notice any symptoms of respiratory distress in your cat or if they have come into contact with rodents, seek veterinary care immediately.

It is crucial to note that there is currently no cure for HPS in cats. Treatment mainly focuses on managing symptoms and providing supportive care. So, prevention is the best course of action.

Apart from HPS, cats can also contract other diseases from mice, such as Leptospirosis, Tapeworms, and Salmonella. Therefore, keeping your cat up-to-date on their vaccinations and regularly checking in with your veterinarian can help keep them healthy and safe from these potential illnesses.


Leptospirosis, a bacterial infection, poses a serious threat to cats. The disease can be transmitted to them through contact with infected rodents or contaminated water, soil, or food. If left untreated, the bacteria responsible for this illness can cause severe damage to the liver and kidneys, leading to organ failure.

To prevent leptospirosis in cats, there are several measures that cat owners can take:

  • Minimize exposure to infected rodents: Keeping homes and surrounding areas free from debris and waste can help reduce the risk of rodent infestations. Using sealed containers for food storage and sealing entry points where rodents could enter the home is also important.
  • Keep cats indoors: Indoor cats have a lower risk of exposure to infected rodents and contaminated environments. However, if cats are allowed outside, they should be closely monitored and kept away from areas where rodent activity is high.
  • Vaccinate cats: Vaccination against leptospirosis is available for cats who are at high risk of exposure. Discuss with your veterinarian if your cat is a good candidate for this vaccine.
  • Seek veterinary care immediately: If you suspect your cat has been infected with leptospirosis, it’s crucial to seek veterinary care immediately. Early treatment can help prevent serious complications and improve your cat’s chances of recovery.

Symptoms of leptospirosis in cats include fever, vomiting, diarrhea, lethargy, loss of appetite, jaundice, and bleeding disorders. Prompt attention to these symptoms can help save your cat’s life.


These flat, ribbon-like worms reside in the intestines of animals, including cats. The primary cause of tapeworm infection in cats is through the ingestion of infected fleas or by consuming the flesh of an infected animal, such as a mouse.

Once inside the cat’s intestine, the tapeworm larvae attach themselves to the intestinal wall using hooks or suckers and grow into adult worms. Over time, they produce segments called proglottids that contain eggs. These segments break off and exit the cat’s body through their feces.

While tapeworm infections in cats may not always show noticeable symptoms, they can lead to vomiting, diarrhea, weight loss, and a swollen abdomen. Cats may also experience itchiness around their anus due to the presence of tapeworm segments. In severe cases, tapeworms can cause blockages in the intestine or interfere with nutrient absorption.

To prevent tapeworm infection in cats, it is essential to keep them away from rodents and other small animals that could be carriers of the parasite. Regular deworming is also recommended for outdoor cats who may have a higher risk of exposure. Treatment for tapeworm infection typically involves medication prescribed by a veterinarian.


This type of bacteria is commonly found in the intestines of mice and other rodents that cats love to hunt.

If your cat comes into contact with infected mice or their feces, they may contract salmonella, which can lead to uncomfortable symptoms such as vomiting, diarrhea, and fever. However, it’s not just cats who are at risk – they can also transmit the bacteria to humans through their feces. That’s why it’s crucial to practice good hygiene when handling and disposing of cat litter.

Prompt veterinary care is essential if you suspect your cat has contracted salmonella. Thankfully, antibiotics can treat most salmonella infections effectively. It’s essential to seek veterinary help immediately if your cat exhibits any symptoms of salmonella.

Prevention is the key to keeping your feline friend healthy and safe from infections like salmonella. Here are some steps you can take:

  • Keep mice out of your home by sealing any cracks and holes in your walls and floors.
  • Properly dispose of any mouse droppings or dead mice.
  • Feed your cat a high-quality diet to boost their immune system and reduce their susceptibility to infections.

Prevention and Treatment of Mouse-Related Diseases in Cats

Our feline companions have a natural inclination to hunt, but this instinct comes with potential risks. Mouse-related diseases such as salmonella, hantavirus, and leptospirosis can be harmful not only to our cats but also to humans. Therefore, it is crucial to take preventative measures and seek veterinary care immediately if necessary.

One effective way to prevent mouse-related diseases in cats is by keeping them indoors. Indoor cats are less likely to come into contact with rodents and other potential sources of infection. This reduces the risk of disease transmission and keeps your cat safe from other outdoor dangers. However, if you allow your cat to roam outside, it’s important to keep an eye on their behavior and any potential signs of illness.

Maintaining a clean living environment is essential for your cat’s overall health and well-being. Regularly cleaning their litter box, food and water bowls, and bedding helps reduce the risk of exposure to bacteria and other harmful substances that mice can carry. In addition, it’s important to take immediate action and eliminate any rodent infestations in your home.

If you suspect that your cat has contracted a mouse-related disease, it’s critical to seek veterinary care immediately. Early diagnosis and treatment can improve their chances of recovery and prevent the disease from spreading to other animals or humans in your household. Treatment for mouse-related diseases in cats may include antibiotics, fluids, and other supportive care measures.
