A cat sees about 6 times better than a human at night, and needs 1/6 the amount of of light that a human does - it has a layer of extra reflecting cells which absorb light.

Very creepy yes.

Cats' hearing stops at 65 khz (kilohertz); humans' hearing stops at 20 khz.

I wonder what they hear.

A healthy cat has a temperature between 38 and 39 degrees Celcius.

Nobody will hear us here

but it's still very good to know!

A cat's whiskers are thought to be a kind of radar, which helps a cat gauge the space it intends to walk through.
