You feed them with free food stuff like omelette and jellies. Foods free from Tombola and other free daily doings.
Kinnda depends on which pet you're talking about. XD; Some I dump into the Neolounge, others I leave to starve.
LOL, that bothers me too. Usually I just feed them when I have extra food cluttering up my inventory, like if I won something from a game or wheel and it isn't worth anything, or if I feel like stopping at the Giant Omelette or Jelly mountain thing. Hey, if it's free food... why not?
Or you could say you dump them in the neolounge so they can get bloated automatically without the need to feed them..
i only feed them because its annoying to look over and see that my pets dying every couple days so i go threw my saftey deposit and pick out a bunch of junk for it to eat.. and then he gets really bloated.. and its not so annoying for a couple days haha Unleashable
