WiFi APs do not have a power output of zero. Think about it for a minute, it makes no sense whatsoever.

"Zero, give or take measurement errors." As related to the GP's assumption "seems a bit harsh to the cat" - in other words, "why are you microwaving your cat, you monster!!111!", not as related to data transfer.

Edited to add the direct quote.

"Zero, give or take measurement errors." Still does not make any sense. It's completely wrong.

Oh, okay, that makes sense; I have misread it as a rhetorical question, then.

The answer is "no, your cat won't get its brains cooked, not even after prolonged exposure" - there's not even enough juice in the battery to do that :)
