If a cat eats rat poop, it risks ingesting parasites (like roundworms, tapeworms, or Toxoplasma) and bacteria (like Salmonella, Hantavirus) that cause severe illness, including vomiting, diarrhea, organ issues, or even neurological problems, so it's crucial to contact a vet if you suspect this happened, as some infections are zoonotic (can spread to humans).
Hantavirus is a very serious disease carried in infected rats and rat droppings. Oddly enough, dogs can develop antibodies to the virus, and cats do not seem particularly affected either.
Initially, cats do not show signs of anticoagulant rodenticide poisoning. After ingesting this type of bait, it takes 1–2 days for clotting factors in the body to be used up. Next, it takes 3–7 days before signs of poisoning occur due to blood loss.
Hantaviruses are a family of viruses which can cause serious illness and death. You can get hantavirus from infected rodents or their droppings. Avoiding exposure to rodents and their urine and feces is the best way to prevent infection. When cleaning up after rodents, special steps should be taken to avoid exposure.
Leptospirosis: This bacterial infection is transmitted through mouse urine and can cause jaundice, fever, and muscle pain. Hantavirus: While rare, hantavirus in cats can occur if your cat encounters mice or their droppings.
What are the signs of toxoplasmosis in cats?
Two of the most common diseases transmitted from rodents to cats are : Tapeworms - eg Taenia, Diplopylidium, Echinococcus, Hymenolepis and Spirometra.
Rats are attracted to houses primarily by easy access to food, water, and shelter, especially warm, cluttered, and dark spaces like attics, basements, and wall cavities, with common attractants including unsecured garbage, pet food, birdseed, fallen fruit, leaking pipes, and clutter like cardboard boxes or woodpiles that provide nesting sites. Sealing entry points, removing food/water sources, and reducing clutter are key prevention steps.
Symptoms and Severity
Symptoms of hantavirus typically develop 1-8 weeks after exposure to rodents or rodent droppings and may be non-specific, including fever, fatigue, muscle aches, nausea, and cough.
In most recorded cases, symptoms develop 1 to 8 weeks after exposure. Early symptoms, such as fever, dry cough, body aches, headaches, diarrhea and abdominal pain, are similar to many other viral illnesses. This may prevent an HPS diagnosis before the illness progresses.
This is because rats and mice are nocturnal animals and tend to come out around 12am – 3am looking for food. If you do see rats or mice in the daytime then you have a much larger problem.
In most cases, cats can recover without incident from poisoning and go on to live long, normal, healthy lives. In other cases, such as cats that develop kidney failure from ingesting lilies or ethylene glycol in antifreeze, there may be permanent damage to internal organs from the poisoning.
The Top 5 Poisons Of Cats
The number one killer of cats depends on age and lifestyle, but cancer is the leading cause of death in older cats, while Feline Leukemia Virus (FeLV), accidents/trauma (especially for younger cats), and diseases like kidney/heart issues are major factors, with FeLV often cited as the top infectious killer. Causes range from diseases like FeLV, Feline Immunodeficiency Virus (FIV), and FIP, to organ system failures (kidney, heart), and external factors like poisons or trauma.
Symptoms of rat poison intoxication in cats
It's possible to repel rats using essential oils such as peppermint oil and other smells that they naturally don't like. Using peppermint oil is one of the easiest ways to keep rats away from your home as long as you aren't giving them an easy food source.
Rat droppings are one of the main causes of food borne infections. Hantavirus is a common dangerous disease which is present in rat droppings. Hantavirus activity duration is dependent on environmental conditions such as temperature and humidity. Usually it is only 2-3 days.
Symptoms of leptospirosis may include:
It can also lead to multi-organ failure, including the kidneys, and is associated with high mortality. However, if the patient can be successfully support through this phase, recovery can be quite rapid with no long-term consequences.
Rats hate strong, pungent odors including peppermint, eucalyptus, citronella, and predator scents like coyote urine. Ammonia-based odors and capsaicin also create aversion responses.
Look for signs of rat or mouse infestation: Rodent droppings around food packages, in drawers or cupboards, and under the sink. Nesting material such as shredded paper, fabric, or dried plant matter. Signs of chewing on food packaging.
Wild rats are not used to human contact and will bite when handled or when people attempt to feed them by hand. The nocturnal creatures have also been known to bite sleeping people, particularly children and infants, on exposed body parts such as fingers, hands, toes and the face when foraging for food.
The top "silent killers" in cats are Chronic Kidney Disease (CKD), often going undetected until 75% kidney failure, and Hypertension (High Blood Pressure), which damages organs without obvious signs until blindness or seizures occur, notes Muirfield Animal Hospital, Pet Health Network, www.springwoodvets.com.au, Close Veterinary Clinic, Killarney Animal Hospital, Physicians Mutual Insurance, Sykesville Veterinary Clinic, Mona Vale Veterinary Hospital, Nimbus Pet Hospital, Hill's Pet Nutrition, Covetrus North America, ASPCA Pet Insurance and PetCareRx. Other serious conditions include Hyperthyroidism, Heart Disease (like HCM), and Fatty Liver Disease (Hepatic Lipidosis).
Whilst catching a mouse or a rat may be a natural activity for cats and in some cases, dogs, eating rodents can have undesirable consequences on our pets. Dangers include infection from intestinal worms and/or toxoplasmosis as well as the possibility of suffering from secondary rat bait poisoning.
A cat's "worst enemy" depends on context, but common foes include dogs (due to predatory instincts), loud noises (vacuum cleaners, thunderstorms), other cats, and cars for outdoor cats; in the wild, it's larger predators like coyotes, birds of prey, and even other felines, while cancer is a leading cause of death for indoor cats.
