Vitamins A and C

Vitamin A ensures that the eyes remain in good condition, while vitamin C is an excellent source of immunity and energy that can be used to fight off illnesses and infections. Guinea pigs require a sufficient quantity of vitamin C to maintain their health and avoid scurvy as well as other illnesses.

How to Feed Blackberries to Guinea Pigs?

Hello, I am Rick Matthews, I have helped raise 100's of pets in my life living with my Father who while we did not live on a farm, raised all sorts of animals to sell them to families. We had so many different pets we all quickly became experts intending to them and helping them stay healthy. Back then we did not have the internet to look up thing on how to take care of their kids. As my kids got older, they wanted pets and of course, I did not want to have as many as we did when I was a child, but wanted to share my experiences. Many of these articles are written to help educate families on what to expect when looking to get a new pet for their children.
