hey .. leave the guinea alone for a few days and let him get used to his surrounding ok..

they need alot of vitamin C so give him lots of veggies like a bowl full in the morning and a bowl full at night...

put the cage in a room not being used for they are nocternal and make sqeeling noises at night when they are most vercherious..

they get lonely very often so hold him all the time .. have a towel on you lap when you cuddle him because they pee ALOT..

when they are exsited scared or whatever they make i hight picked squeeling sound thy sound like a pig.. thats why they are called guinea PIGS.. dont be alarmed if it does this the first time you play with him.. he doesnt know you and i would scream if some strange gaient picked me up wouldent you ?? lol so just be VERY gentle with it ok and oh ya have funnn !! lol
