We had just gone away for a night in london and we obviously had to leave the guinea pigs. When we came back we were really excited to seeing them and so were they! we held pop first and then i washed my hands and held crackle in the same place. now because they have been seriously fighting we had to separate them. so when i held crackle even though pop hadn't weed he got really worked up and started chattering his teeth. i then moved and he started digged at my top where pop had been! he got so worked up i had to change my jumper. Poor crackle, they really don't like each other!
