It's cute and there's nothing you can do about it.
Izzy has two purrs, there's her contented comfy purr she does when settling in for a nap, and she's got her guilt purr which she does about an inch from my eyeball when she wants her breakfast. It's a noise she can make continuously for hours that is simultaneously irritating and adorable.
Or she throws things.
Tell Izzy I said psps.
She says "mrow?"
