flushing kitty litter down the toilet
This is one of many warnings about flushing kitty litter and/or feces down the toilet:
According to Dr. Melissa Miller of the California Department of Fish and Game, cat feces can contain Toxoplasma gondii, a parasite that gets into feline systems from the eating of infected rodents, birds or other small animals. When cats later expel these parasites in their droppings Â sometimes hundreds of millions at a time Â each can survive in soil for over a year and also contaminate drinking water.
Most municipal sewage treatment systems are not designed to filter out Toxoplasma, and so the parasites also get into storm drains and sewage outflows that carry them out to near-shore ocean waters. Here, researchers have found, sea otters prey on mussels, crabs and other filter feeders that can concentrate Toxoplasma. Hundreds of sea otters have been found dead on California beaches in recent years with no obvious external injuries, and Miller and other scientists think that Toxoplasma may be the cause.
