From looking at the back of the cat food packs our kits should be moving to eating less food now they are verging on 7 months. But they both seem starving about 2 hours after breakfast and most of the afternoon. They have been having 3 meals, so I think we may keep this up (not sure when we should be moving to 2 meals) even if it's a bit less total food. The boy is much bigger than the girl and scoffs his food then dives into hers, like we have been starving him. Then an hour or two later they both act like no one has fed them. Is this just chancing their arms/paws or are some cats just hungrier than others? Should we feed the bigger one more or is he bigger because he steals from his sister??? Advice appreciated! Thanks
