We received 2 Guinea Pigs 6 weeks ago that were "babies". They came from a Pet Store ( I had no idea we were receiving them as a gift, have since found out pet store piggies are adding to the problem). Anyway the piggies are healthy and marginally friendly. My question is as follows. I feed them unlimited Timothy hay and water, they have grown quite a bit since we got them. They get 2 cups of veggies per day. I feed 1/4 cup of alfalfa based pellets per day. Sometimes my teenagers give them more "cereal" if they notice their pellet bowl is empty ( they refer to the pellets as piggy cereal). The piggies are starting to look a bit chubby in my opinion. Especially my fuzzy longish haired piggie. Any advice? Are the piggies chubby, or are they simply growing? I don't want them to be unhealthy and I feed plenty of veggies that are high in vitamin C and even switched to a 2*4 C&C cage as well as fleece bedding to make them more comfortable/allow space for exercise.
