My SO and I recently adopted a pair of six month old kittens, and we're trying to work out how much to feed them. (We have an older cat, but she's not relevant here, yet.)
Currently, we're feeding them a half cup of dry kibble four times a day (total: 2 cups), with occasional canned wet food. When we feed them, they both gobble it all down quite happily (every last piece of kibble), and a few hours later are mewing at us for more. It's extremely rare for them to actually leave any food behind.
Should we be feeding them more (within reason), to the point that they seem to have sufficient food? Should we just ignore the mewing for more feeding? Experiment to see how much they actually want? We don't want them to become overweight, but we don't want to keep them constantly hungry, either.
