Giardia is a tiny parasite that causes big problems in your cat’s digestive system. It’s one of the most common intestinal parasites found in cats, affecting both indoor and outdoor cats alike.
When Giardia enters your cat’s system, it attaches to the lining of the intestines, where it disrupts the normal absorption of nutrients. This disruption leads to the symptoms commonly associated with giardiasis, such as diarrhea and weight loss.
While the condition is more common in vulnerable cats, such as kittens, older cats, and cats with health issues, any cat can become infected.
What Causes Giardia in Cats?
Cats typically become infected with Giardia by ingesting the parasite's cysts, which can be found in contaminated water, food, or feces. Let’s break down the most common ways your cat might come into contact with these parasites:
Contaminated Food and Water
One of the primary sources of Giardia infection is contaminated water. If your cat drinks from puddles, streams, or other bodies of water that have been exposed to infected feces, they can ingest the cysts. These sources of water are most likely found outdoors and in your yards and gardens, or if their water bowls haven’t been cleaned for a long time.
Contact with Infected Feces
Giardia can also spread through direct contact with infected feces. For example, if your cat steps in contaminated soil or litter and then grooms themselves, they can ingest the parasite. This is why keeping the litter box clean and properly disposing of waste is important for keeping your cat’s overall health in check.
Environmental Contamination
The cysts of Giardia can survive on surfaces like bedding, food bowls, or even your hands if you’ve been in contact with contaminated material. This means that even indoor cats can be at risk if their living environment is not properly sanitized.
What are the Symptoms of Giardia in Cats?
Giardia can trigger a whole range of symptoms in your cats, although not every cat may show any sign at all. One of the most common signs is diarrhea, which can be chronic or irregular. Knowing the symptoms is crucial in getting your cat the expert vet care it needs. Here are some of the most common signs of Giardia in your cats:
Diarrhea
Diarrhea is often the first and most noticeable symptom of Giardia in cats. Their stool may be soft, watery, or contain mucus and blood. Prolonged diarrhea can disrupt your cat’s daily activity and is a sign for veterinary action.
Weight Loss
Giardia interferes with nutrient absorption, which prevents our cats from getting the nutrition they need to get better and stronger. Infected cats may lose weight even though they follow their feeding routine and don’t lose their appetite. This weight loss can be gradual or rapid, depending on the situation and condition of your cat.
Lethargy
Infected cats may become less active and seem more tired than usual. They may feel the want to just lie down for longer periods of time, hindering their physical activities. This lethargy is often due to the discomfort caused by the parasite and the body’s efforts to fight the infection.
Abdominal Discomfort
Another common sign of Giardia in cats is the presence of discomfort and pain in the abdomen. Cats can moan and be noticeably distressed when they have stomach pains and issues. This discomfort comes from the irritation and inflammation caused by the infection of the parasite in the cat’s intestines.
Vomiting
While less common, some cats may vomit as a result of the irritation caused by Giardia in the digestive tract. Vomiting, combined with diarrhea, can potentially create more problems, such as dehydration. When these two symptoms arise, it’s important to seek emergency vet care.
How to Diagnose Giardia in Cats
If you suspect your cat might have Giardia, we recommend visiting our clinic. Diagnosing Giardia typically involves a few different tests, as the parasite can be tricky to detect.
Fecal Examination
The most common diagnostic method is a fecal examination, where our vets will analyze a sample of your cat's stool under a microscope to look for Giardia cysts.
However, because these forms of the parasite can be elusive, multiple samples over several days may be needed to increase the chances of detection. Time is needed to create an accurate diagnosis of your cat’s condition.
Fecal Flotation
Another method is fecal flotation, which involves mixing the stool sample with a special solution that makes the Giardia cysts float to the surface. This process makes it easier for our vets to identify the cysts under a microscope. Once we identify the cysts, we can confirm Giardia in your cat and proceed to treat it.
ELISA Test
The Enzyme-Linked Immunosorbent Assay (ELISA) test is a more advanced diagnostic tool that detects specific antigens associated with Giardia in the cat's feces. This test is highly dependable and can easily confirm the presence of the parasite even if it isn’t visible under the microscope. If the is positive, it confirms the presence of Giardia in your cat.
How to Treat Giardia in Cats?
When treating Giardia in cats, the process is a long, step-by-step medication plan that requires cooperation on both our parts. The use of medications, treatments, and recovery techniques is important to make sure your cat’s Giardia will be treated. Here’s a simple flow of treating Giardia in cats:
Medications
The primary treatment for Giardia in cats involves the use of antiparasitic medications. Our vets will recommend the appropriate medicines and doses to help treat your cat.
Metronidazole
Metronidazole is one of the most commonly prescribed medications for treating Giardia in cats. It’s an antibiotic with antiparasitic properties that works by disrupting the DNA of the parasite, effectively killing it.
Typically, metronidazole is administered for five to seven days, depending on our analysis of the situation. While it’s generally effective, it is a pretty strong drug. Some cats may experience side effects such as nausea, vomiting, or decreased appetite. If your cat shows any prolonged side effects, it’s time for a quick kitten visit.
Fenbendazole
Fenbendazole is another antiparasitic medication often used to treat Giardia, especially in cases where metronidazole alone isn’t sufficient. This can be given along with metronidazole as a good combination can be effective. It’s usually given over a period of also five to seven days, but this can vary.
Fenbendazole is generally well-tolerated by cats and has fewer side effects than metronidazole, making it a preferred option for some vets for cats with sensitive bodies.
Supportive Treatments
Along with robust medications, there are some natural treatment options that can aid and speed up the recovery process for your cats with Giardia.
Dietary Changes
When your cat gets an upset stomach from Giardia, we would typically recommend a change in diet to help your cat have an easier time with eating. An easily digestible and low-fat diet would help alleviate your cat’s gastrointestinal symptoms and support its gut health.
We recommend avoiding rich or fatty foods to reduce the strain on your cat’s digestive system, which is already working hard to fight off the parasite.
Probiotics
Probiotics can be beneficial for restoring healthy gut flora, especially after a Giardia infection. These supplements help replenish the beneficial bacteria in your cat’s intestines, which can be disrupted by both the parasite and the medications used to treat it.
Before giving your cat some probiotics, make sure to check with us so we can make sure your cat can have probiotics safely.
Hydration
Keeping your cat well-hydrated is crucial, especially if they are experiencing diarrhea and vomiting. Dehydration can quickly become a serious issue and cause more health problems, so it’s important to provide clean and fresh water all the time.
To make it worthwhile, you can offer wet foods to give your cat a boost in nutrition while also helping it increase its fluid intake.
How to Prevent Giardia in Cats
Preventive measures can go a long way to keep your cat healthy and happy. Not only do these steps help keep your cat safe from Giardia, but they also help prevent various health issues. Here are a few ways to prevent giardia in cats:
Provide Clean Water
Make sure your cat has fresh, clean water. Replace the water in their bowl at least once a day and wash the bowl regularly to prevent contamination. Consider using filtered or bottled water, especially if you’re unsure about the quality of your tap water.
Keep A Clean Area
Regularly clean your cat’s sleeping and playing area. Clean the litter box, disinfect surfaces, and wash bedding and toys to help keep your cat’s area squeaky clean all the time.
Observe Proper Cat Hygiene
Grooming is a significant part of your cat’s lifestyle. Regularly groom and bathe your cat, especially long-haired breeds. If you want a professional cat grooming service, our doors are always open to you.
Diet and Nutrition
Provide a balanced and nutritious diet for your cats to support their immune system function. A healthy immune system is a good defense for infections like Giardia.
Conclusion
Giardia is a common condition that can cause abdominal discomfort and distress for your cat. By understanding the causes, recognizing the symptoms, and following the appropriate treatment and prevention steps, you can help your cat get better and stay healthy. Remember, early diagnosis and treatment help keep your cat smiling!
