Cats can jump surprisingly high, slip through the tightest spaces, and seemingly have nine lives.

But there's one thing they can't do: taste sweet things.

According to a 2007 article in Scientific American, unlike other mammals, felines can't taste sweetness due to the fact that they "lack 247 base pairs of the amino acids that make up the DNA of the Tas1r2 gene.

As a result, it does not code for the proper protein … and it does not permit cats to taste sweets."

I was reading about squirrels today. Male squirrels don't like baby squirrels, so they build a private den in the nest and stay until the children get old and move out.

The proper name for having two differently colored irises such as one green eye and one blue is heterochromia iridum, or more commonly heterochromia. In individuals with heterochromia the melanin pigmentation is not uniform in distribution and concentration.

Heterochromia is not always complete, you can have sectoral heterochromia. This is when just one part of the eye's iris is a different color I.e a brown eye with flecks of gray.

In hazel eyes the melanin distributed is always irregular. This eye is not truly brown or amber, or green or blue, It can have patches of those colors but it isn't one solid color.

Changes to the color of the body pigmentation is a characteristic of the genetic disorder Waardenberg syndrome. People with this condition often have unusual, large, wide set blue eyes or heterochromia with one blue and one brown. Heterochromia may be present not only in the eyes but hair or skin. There may be a patch of white in a dark head of hair or splotches of discolored skin in individuals with Waardenberg syndrome.

There are a lot of different subtypes of waardenberg, some are more extreme then others, many cases are benign, but medical conditions like deafness or spinal cord defects may be present in it's more severe forms.
