Caring for a Cat Giardia Patient

"Caring for a cat giardia patients starts with an understanding of the disease spreads, which is through cysts found in cat feces. The cysts when ingested turn into parasites which negatively affect the digestive tract, making it difficult for some cats to absorb nutrients. Not all cats show symptoms. In cats that show symptoms, they tend to be mild and include diarrhea, weight loss and soft, foul smelling feces. Cats respond well to prescription medications, although they can have side effects. Natural remedies and supplements can be used to help the cat naturally eliminate parasites and restore digestive health. Use under the advice of a veterinarian. To prevent reinfection of the cat, and infection of other pets and family members, shampoo the cat and wash all dishes and the litter box before treatment begins."

Giardia is a common infection in cats.  It is found in 15% of house cats and tends to be seen in younger cats.  It is a protozoa that lives in the small intestine. The disease is spread when your cats mouth comes in contact with feces, from contact with other cats, or by drinking from streams. Cysts from the feces can attach themselves to cat hair making it easy for the disease to spread from cat to cat.

It is possible for some types of feline giardia to infect people, so be sure to wash your hands if handling an infected cat.

Symptoms of Cat Giardia

In most cases giardia will either cause no symptoms or diarrhea. The complete list of symptoms include:

Diagnosis of Feline Giardia

Diagnosis is made through stool sample testing, examination under the microscope, tests for proteins in the stool and feces floating techniques. The condition is difficult to diagnosis, with repeated tests often needed. Testing is important in order to reach a differential diagnosis from conditions that have similar symptoms such as feline coccidiosis.

Treatment of Feline Giardia

Three different drugs are commonly used for treatment:

If metronidazole is prescribed ask your veterinarian about potential side effects such as liver disease and vomiting.

It is important to clean your cat's environment to avoid reinfection.  Since the disease is spread from cyst in the feces that can accumulate in your cats hair, be sure to shampoo them thoroughly.  

There is a vaccine for giardia, however it is not usually recommended because symptoms of this condition tend to be mild.  

You can also supplement your cat's diet with a natural giardia remedy that encourages resistance to parasites and that can help to speed healing, hopefully reducing the amount of time prescription medications are needed. Other helpful homeopathics include Natural Moves, and Digestive Support. Each is formulated to support the digestive system and restore your cat's health.  Be sure to consult with your veterinarian so that he or she can monitor progress.

In addition to any prescription medications and natural remedies, your veterinarian may recommend switching to a highly digestible GI diet. Probiotic supplements can also help to restore the digestive system back to the condition before the cat giardia infection started to change system function.
