Oh no it's not that small of a store. It's a PetSmart, lol. They just have a weird selection of foods for a chain store. They have Royal Canin and Blue Buffalo which I see suggested a lot, but I'm just not sure if I should go for a kitten or adult food. I hear kitten food is hard to wean them off of sometimes.
The reason I mentioned his parents were 500 grams is just because I figure he'll be close to that weight. The breeder doesn't particularly like smaller hedgehogs for breeding.
