Does pressing a key on a wireless keyboard use the battery

[Red Squirrel]

If the PC is off does a wireless keyboard go in "sleep" mode and only poll to see if pc is on, or is it still using the battery?

My cat is sitting on one right now... is that draining the battery? lol

Yes.

yes. any button press activates the transmitter in the KB.

Good to know, I should teach my cat about beds and how they're way more comfortable then a keyboard.
