My bengal Krishna is very greedy and a bit of a bully. If left unattended he will start to eat his, eat about 3/4, then try to shove either of the 2 girls (Maine Coons) out of the way to eat theirs. The more confidnet Coon will stand her ground but the other (Polly) will get shoved out and will then eat the rest of his. Feeding times are now usually supervised or separated. Fortunately, he's less keen on the dry biscuits I buy for Polly, so he won't usually scoff those. If left with biscuits he likes, he will eat until he is sick, then will continue eating more. And repeat. So again, supervised feeding.
Krishna is very vocal about when feeding time is. He's also good at giving me (and anyone else) the 'I've never been fed in my whole entire life; I'm wasting away' look. Unfortunately he also knows how to open doors and cupboard doors* so I have to keep the food in a locked cupboard.
*and the lift, but that's another story
