Our three cats, Polly, Bramble, and Towser, are fitted with internal clocks which tell them when it's time for breakfast and tea. They all just appear at 4pm for their tea. (Breakfast is easy, they hassle me when I get up, never Jim, though, they recognise early morning unconcious)
They don't acknowlege Greenwich Mean Time, though, so start gathering at 3, now.
The dogs, well, Tess, really, play mind games with food, like everything else. She will ignore the food put out for her, and forbid Benson to touch it until she thinks we're not interested any more, THEN she will pick the best bits out of both bowls before retiring, and allowing Benson to eat.
She is a collie cross, and it's fascinating watching her pick up tiny signals and act on them, but that's another story. Hwyl, Bron.
