1) Instead of waiting for food at the food store, click on the Art Gallery. There’s a coffee shop in there, and coffee feeds your pet a little bit more than a regular food item would have. Although it’s a bit more expensive (rounding 60 Np-500 Np), its worth your while.
2) Why even feed your pet when there’s an even more efficiant way to feed? The Neolodge will house you pet for about and month for just 140 np! Simply go to the Neolodge, book you pet into Cockroach Towers for 28 days and you’re done for a month! – shoyruhotte
