Giardia in Cats

Giardia is a single-celled parasite that nests in the intestines of cats. The parasite is transmitted through the ingestion of food, water, or feces contaminated with the eggs of the Giardia parasite (cysts). Cats can also become infected through close contact with other infected cats. Once the parasite is inside the cat's body, it attaches to the intestinal wall and multiplies rapidly, which can lead to various health problems. Moreover, an infection with Giardia does not necessarily lead to diarrhea; research in healthy cats with normal stool has shown this intestinal parasite to be present in the feces of as many as 14% of cats! About 20% of cats with diarrhea test positive for Giardia. Giardia is relatively common, especially in kittens.

Although it is rare, it is important to know that Giardia can also cause infection in humans, especially in people with a weakened immune system. Therefore, it is crucial to take necessary precautions and maintain good hygiene.

Symptoms of Giardia in Cats

Your cat can be a carrier of Giardia without you or your cat noticing anything. In other cases, your cat may become ill from this single-celled parasite. The most common symptoms are:

• Diarrhea: the stool is softer, sometimes greasy or slimy, and can have a strong odor. You may also notice that your cat goes to the litter box more often or has trouble holding its stool. Sometimes the stool is lighter in color. Of course, there are multiple causes for diarrhea in your cat. At Pharmacy4Pets, we offer various products that help keep the stool firm.
• Decreased appetite
• Abdominal pain
• Vomiting: usually only diarrhea occurs, but sometimes Giardia can also cause vomiting in cats. A cat with Giardia may also vomit.
• Weight loss: in more prolonged infections, your cat can lose weight due to the loss of nutrients and decreased appetite.
• Poor coat condition: a dull coat and overall poor coat condition can indicate an infection with Giardia.

Diagnosis of Giardia

If you suspect that your cat is infected with Giardia, it is important to consult a veterinarian for an accurate diagnosis. The vet can examine your cat's feces for the presence of the Giardia parasite or its cysts. Sometimes it may be necessary to collect multiple stool samples, as the parasite is not always visible in each sample. Typically, a mixed sample from three days is advised for examination.

Treatment of Giardia

The treatment of Giardia in cats usually involves the prescription of an antiparasitic medication by the veterinarian and advice regarding hygiene.

Antiparasitic Medication

Panacur, a deworming medication containing Fenbendazole that is also effective against Giardia, is the first-choice treatment. In some cases, an antibiotic is advised.

It is important to administer the prescribed medication for the full duration of the treatment, usually three to five days, even if symptoms improve.

Hygiene

Good hygiene is crucial to prevent re-infection with Giardia. The intestinal parasite remains present in the environment for a long time. It is important to thoroughly clean your cat's environment: litter boxes, food and water bowls, and other surfaces should be regularly cleaned and disinfected. It is also advisable to clean your cat, especially the anus, daily with a washcloth. Washing your entire cat is usually not necessary and can be very stressful for your cat. Try to prevent your cat from drinking outdoor water and licking feces or grass.

Nutrition

If your cat is infected with Giardia, it may be beneficial to feed a highly digestible diet such as Sanimed Intestinal Cat to support the intestines and promote your cat's recovery. Also, probiotics can help restore balance in the intestines.

If you suspect that your cat is infected with Giardia, consult a veterinarian for an accurate diagnosis and treatment. Strictly follow the prescribed medication and ensure thorough cleaning of the environment to prevent re-infection. With the right care and treatment, your cat can recover well from Giardia and enjoy a healthy and happy life again.
