Bea will usually eat everything in sight but lately (since we got the kittens) will only eat at long as the kittens aren't bothering her.
Chloe is tiny and will only eat a tiny bit at a time
Berach eats anything in sight and will chase the others off to eat their food too.
Lord... I sympathize
I feed them altogether when I can and I feed them at least three times a day or more (but never more than what they should have for their size for the day). If either of the kittens bother Bea while she's eating I put them in the other room until she's done. If Berach bothers Chloe... same deal.
sometimes you just have to seperate them, besides, it's really only for a couple minutes...
