As most of you know, I have four bottle babies. Estimated to be between 3-4 weeks old (closer to 3 than 4). They're doing great, taking the bottle just fine. With the kittens I've bottle fed in the past, they've all let me know when they're hungry. Every 3 hours, like clockwork, they'd start screaming. But these kittens are different. I fed them before bed last night and kept waiting to hear them scream to be fed the rest of the night. I woke up four times in the middle of the night and they were sound asleep every time. They finally started yelling for food at around 7 a.m. My question is... do I wait until they ask to be fed, or should I wake them up and feed them anyway?
