So right now I have 2 female Guinea Pigs I got from a friend there both 7 weeks I just got them a C&C cage it's a 3x5 and they where popcorning and doing laps all night lol. So is there anything I else I should get them there bedding is Carefresh natural and i feed them Oxbow pellets cause I saw that they where really good and I also feed them western cut timothy hay they adore it and devour it in there hay rack.I also feed them cut up celery 3 times a week with some of there dishes,everyday I give them 2 baby carrots each and 2 leafs of fresh lettuce each everyday. I got them a cuddle cup and a hammock/tent and last night I got them a igloo also if anyone wants to reccomend something else please do so .

Yes the pictures below are them Luna and Zoey yes I know its a pet store cage but this was taken when I first got them they are now in a 3x5 so dont worry there in a better cage:silly: oh I also just noticed in the picture it's there mineral lick yes I know its bad they never touched it so thats good I never gave it to them again cause 1rst they didint do anything with it and I saw they where bad.
