My guinea piggy doesn't h have front teeth ,but it is growing in he has a great diet too. He is having trouble eating his carrots and leafy greens. He is also having trouble with eating is food pellets. My other guinea pig CORN CHIP is fine he is a newborn and is very well feed and healthy. He is about 3 weeks old now. MINI MOO is 6 months old much bigger than CORN CHIP. I just really need to now how to feed MINI MOO with the no front teeth.
