As part of a charity event, 500 cats were spayed and neutered in the cafeteria of an elementary school. School was cancelled for days and $10,000 was spent on cleaning and sterilizing the room.

On an American one-dollar bill, there is an owl in the upper left-hand corner of the “1″ encased in the “shield” and a spider hidden in the front upper right-hand corner.

The fingerprints of koala bears (koala resembles a bear, but is actually a marsupial) are virtually indistinguishable from those of humans, so much so that they could be confused at a crime scene

The reason firehouses have circular stairways is from the days of yore when the engines were pulled by horses. The horses were stabled on the ground floor and figured out how to walk up straight staircases.

Homing pigeons use roads where possible to help find their way home. In fact, some pigeons followed roads so closely that they actually flew around traffic circles before choosing the exit that led them home.

Some dogs can predict when a child will have an epileptic seizure, and even protect the child from injury. They’re not trained to do this, they simply learn to respond after observing at least one attack.

While watching her favorite movie, Koko the gorilla suddenly turned away when the saddest scene began, She then signed “frown”,”sad”, “cry”,”bad”, and visibly teared up.

In 1997, a woman in Bradenton, Florida lost her cat. In 2004, she got a call from the local animal shelter. The cat turned up wandering the streets in San Francisco, California. The cat’s identity was proven with a microchip that had been implanted prior to 1997.

Studies show that if a cat falls off the seventh floor of a building it has about thirty percent less chance of surviving than a cat that falls off the twentieth floor. It supposedly takes about eight floors for the cat to realize what is occurring, relax and correct itself.

No animal, once frozen solid (i.e., water solidifies and turns to ice) survives when thawed, because the ice crystals formed inside cells would break open the cell membranes. However there are certain frogs that can survive the experience of being frozen. These frogs make special proteins, which prevent the formation of ice (or at least keep the crystals from becoming very large), so that they actually never freeze even though their body temperature is below zero Celsius. The water in them remains liquid: a phenomenon known as ‘supercooling.’ If you disturb one of these frogs (just touching them even), the water in them quickly freezes solid and they die.

Rats can’t vomit – that’s why rat poison works. Explanation – Rats can’t vomit for several related reasons: (1) Rats have a powerful barrier between the stomach and the esophagus. They don’t have the esophageal muscle strenght to overcome and open this barrier by force, which is necessary for vomiting. (2) Vomiting requires that the two muscles of the diagram contract independently, but rats give no evidence of being able to dissocicate the activity of these two muscles. (3) Rats don’t have the complex neural connections within the brain stem and between brain stem and viscera that coordinate the many muscles involved in vomiting.
