I would have to say that our females all feed more aggresively than males, be they young or older, CB or WC. We have several that are meet you at the door, come out and get it if you aren't fast enough. LOL. We long ago learned to go armed with the rat on long tongs! and to have it ready to go in the door as soon as the latches come up. It's a little scary having a 6 footer come out at you looking for her food. However, I've found younger CB males are nearly as bad about food seeking, neos to 6 years (our oldest CB). It's the WC adult males we've always had problems with, they are really slow about eating and nearly always have to be teased or refuse to eat unless it's live.
