Behold, a truly fantastic gift for the cat in your life — catnip-filled soft toys shaped like amoebas, cyanobacteria, and (pictured above) giardia.
Giardia are microscopic parasites that can invade the guts of vertebrate animals, including cats and humans. Generally, you get it by ingesting giardia-infested feces. For humans, this mostly means contaminated drinking water, because giardia are harder to kill than you might think. They can survive quite happily outside of a host and are resistant to chlorine.
Maggie Rizer, a well-known fashion model, blames United Airlines for the death of her Golden Retriever, Bea, who suffered heat stroke and died during a cross-country flight two weeks ago. From NY Daily News: "Their plane had been delayed in New York and the captain told passengers to turn on their air vents to help circulate air, but Rizer believes gusts of hot air killed her dog in the belly of the plane, where there isn’t the same quality of circulation as there is in the cabin."
