Hi everyone, i have just got my first Guinea pig ever. yeah. his name is frodo and i think i have had him for around 3 to 4 weeks. Although, frody has a problem, every now and them his pee is white, and it drys like white paint. Could this be because if lack of water? He doesn't drink much because his new but only young, but when he does it goes away for a little bit. Any ideas????.
