Ok we got this 7 week old guinea pig this past Friday.We let it calm down until Sunday before we started picking him up.Well he is cool for the most part during these holding times but after about 10 minutes he bites me .Then Laura gets bit within a couple minutes when she tries to get him out to hold him.So does anyone have any suggestions on how to make him stop this biting.Or any ideas why he is doing it .Thanks ahead of time
