Researchers say cat waste hazardous to marine life and humans

Millions of parasites may be crawling in your cat's waste.

Researchers believe those tiny critters can cause disease in marine life and humans. A young cat can shed up to 100 million little egg-like structures in its feces.

Researchers say the parasites get into the ocean through storm runoff, where mussels and other sea creatures may eat them.

In humans, the parasites can cause problems for infants born to infected mothers. Experts say pay attention to how you dispose of your cat's litter and where you get your shellfish.
