Yesterday early evening I went to my colleages house to collect a guinea pig she could no longer look after (it was attacking her other guinea pig). I put it in my carrier and bought it home and put it in the cage I had set up. The cage is the one I use for my outdoor guinea pig when it is cold. It is small (it is only temporary) but has a nice hidden area for sleeping in. I put lots of nice bedding in and lots of food and hay and water and treats and a carrot. He hid all night and didn’t eat a thing. There were no poos round the cage or anything. He seems healthy and is more dconfident being handled than my own guinea pig is. This morninh I tookt he carrot out and put his favourite fresh food in (spring greens). Should I be worried.
