Re: bowl or scatter feed
I do a bit of both. Charlie likes both. He knows where his food bowl is and gets a bit anxious if it's not there (eg when I've taken it out to fill it) - but he also gets very excited about finding food in the substrate and foraging for it. So I put half the usual amount in the bowl and scatter the other half. Also occasionally scatter other bits (just small amounts) - pumpkin seeds, grean oats.
