Mind Puzzler

It’s something they do when they are not just content, but also when they are under duress, such as when they are frightened or in pain. They also produce the subtle rumbling with a consistent pattern and a frequency between 25 and 150 hertz – a range of sounds that studies have shown can improve bone density and promote healing.

What is it?

A pair of smart cookies.
Good Job you two.

I was beaten to the punch, but that would've been my guess too. My Jet loves to purr purr purr for me.

 

[Bina]

Meow, meow....this was an easy one for us cat guardians.
Miss Mitten lays on my lap to watch Criminal Minds, purring the whole time; it's not exactly her
type of show, but she tolerates it.
