Cats purr at the same frequency as an idling diesel engine, about 26 cycles per second.

That's why it's so relaxing.
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.
