Just adding a little two sense on the subject of needing pellets ASAP. 75% of a guinea pig's diet should be made up of good quality grass hay, second most important being veggies at 15% of their diet, and pellets coming in dead last with about 10%. Therefore they are a very very small portion of pigs' diets, if you run out it's no huge rush to buy more, as long as they have hay and water, they can go for a few days without pellets whilst you order some more. I know at one point there was even a topic or something asking if pellets were really needed in a guinea pig's diet, and someone said that scientist are now saying that maybe just hay and veggies is best. However I forgot who/when someone said that, so I don't know how true that info is.
