No, they definitely don't care what I'm doing... I've had Snap bite and hang on for a while hoping that my finger had food on it... They want fed every second of the day... Even right after they have full bellies and wont eat another bite I'll go on poop patrol and then I have one biting at my finger again. It's cute though, especially Snap, she didn't trust me the first week I had her but now when she knows its feeding time she pulls the "put food here!" move on me. If I don't, she snatches it off my finger and pouts in her usual hiding place until she's done eating that piece... Then pulls the same move again.
