Hello we have got a gorgeous new baby guinea pig. Just brought him home today I always had them when I was a child but seem to have forgotten some things and feel pretty nervous I've got him inside as thought it was a bit cold for him to be in his cage but I used hay in the bedding area and my friend says I should of used straw. Will he be ok with hay I just don't want to disturb him as they said at the shop to just leave him to settle for 24 hours. He also hasn't eaten or had a drink yet is that ok. Thank you
