he hasnt been himself for the last couple of days :-\ i moved him outside as my mum didnt want him in the house and 2 days ago my mum came in from work and said 'your white Guinea Pigs just had a sneezing fit' i went outside to check on him he wasnt sneezing anymore and there was no signs of disscharge... he was fine yesturday very vocal and eating like a pig lol but today he seems quite lethargic :-\ i havent seen him eat/drink so far and hes just lying in the corner of his hutch sleeping hes been teh same since i got up at 11 :-\ I'm really starting to worry now... could the sudden change of being in a warm house to the cold outdoors have done this?
