All day long? Are you kidding me? Maybe that's because many human babies never get enough milk via breastfeeding. It sounds as though they didn't know how much (or how little) these tiger cubs actually consumed either.
Nope. We have one that's not quite 3 weeks off the showroom floor that's attached to my wife like a hungry tick whenever she's not sleeping. I told my wife it would have been easier just to leave the umbilical cord attached and carry her around as needed.
