Giardia is a single-celled parasite that can be only be seen through a microscope. It is a common parasite that is passed through fecal material of a infected animal or person. Giardia can be found on surfaces, in food, water, or soil that has been contaminated with fecal material. You can get this protozoa in lakes, river, & pools. The parasite feeds of its host nutrients once it enters the body and can survive several months outside the body. Your pets can get infected with giardia: being in contact with other animals fecal material, rolling on contaminated floors, licking contaminated surfaces, &/or drinking contaminated water. Signs your pet cat has Giardia- possible weight loss, diarrhea, sometimes even excessive vomiting. Your veterinarian can treat giardia with Fenbendazole & Metronidazol.
Coccidia is another common Protozoa parasite that cats can get. Pets can also get this parasite through infected soil or other contaminated conditions. Cats can even get it from hunting infected mice. Coccidia is considerably more dangerous for kittens than Giardia- while infected cats might have watery diarrhea, bloody diarrhea, and sometimes the inability to control their bowel movements. Because it is an infection it can also cause fevers, legarthy,, vomitin, & weight loss that can lead to serious implications and even organ malfunction. Kittens with these symptoms need veterinary care to quickly treat the infection.
