Tapeworms are types of cat worms that are rather difficult to diagnose. A cat can contract these worms when it ingests a flea that has ingested a tapeworm. The likelihood of a cat to contract these worms are very high when the cat has fleas. The worm will come out of the anus and stick to the fur around the bottom. This makes you difficult to notice at the first time. The appearance of this worm is look like grains of white, flat rice. When it gets dry, it gets yellowish color. Some of them can also be noticed in the fecal matter.
