I do the same thing, it comes up to 140 nps per pet. Super cheap. It sucks though.. when I want them to eat something I have in my inventory it says that they are well cared for at the neolodge and dont need to be feed. This is messy when they're avie items like BOP, or Snorkle snout.
I just keep going to the healing spring every few hours and eventually the faerie will cast the spell to make my pet bloated or something.
I keep my pets in the neolodge its pretty cheap and you don't have to feed them and you can also play with them still!! Click here to feed me a Rare Candy! Get your own at Pokeplushies!
The neolodge is indeed a nice, cheap and easy way to keep your pet well fed and happy Used to do that a while back, kept putting them back in
Only recently have I started doing this-- and it's only because, only recently did Neopets start making the pets look sad when you don't feed them!! That irks me for the weirdest reason, so yes, I feed them.
Lately I've started feeding them any food that I have too much of in my shop. (Like half-eaten berries).
Like most people I also put them often in the NeoLodge because it's cheap Although sometimes I feed them with omelettes/jelly.
