Veterinarians estimate that up to 45 percent of felines in the United States are infected with some type of parasite. Feline parasites may be worms such as roundworms, hookworms, or tapeworms or one-celled protozoan parasites such as coccidia, or toxoplasma. Over time, these parasites can leech the life out of a cat, until she becomes too weakened to sustain herself. In addition, there are some feline parasite infections that can transfer from a cat to a human.

Once in the body, animal parasites generally leach nutrients such as vitamins and essential minerals. This nutrient loss can result in severe vitamin deficiencies, anemia, and weight loss.
