Cats that are both inside and outside are in need of
strategic deworming for good health. Insects, mice, birds, snails and other hunted items carry parasites that can be detrimental to the health of the cat. Deworming monthly with Heartgard for cats will take care of many of the parasites, this is a monthly treatment. The CDC recommends deworming cats every three months in a strategic move to keep parasites from establishing in the cat. A "fecal" or "Worm check" is a screening technique that is not foolproof...20% of the fecals checked will be false negatives. The rule of thumb for fecals is that a minimum of five tests that are negative for parasites is the only way of determining that the cat is 90% negative for parasites...its easier to practice
strategic deworming for the cat's health.
We have been doing this in my practice for over 16 years because of the parasite population here in the SE US.
