Safety Information and Key Tips to Feeding Grass to Your Guinea Pig 

Although guinea pigs are relatively tame and easy to take care of, it is important to take care of them properly to ensure optimal health and happiness for your furry friend. What you feed your guinea pig affects their health and happiness.

Below are some key tips to help ensure your guinea pig eats their desired grass safely. 

  • When letting your guinea pig explore grassy areas, allow them to explore for up to 10 minutes. After 10 minutes, assess if they are visibly displaying allergies including trouble breathing and swelling. 
  • Guinea pigs do not produce their own calcium, this means they need it from a supplement. Grass contains high levels of calcium and is one of the big reasons they are a popular food choice for guinea pigs. 
  • Hay is a more sustainable snack for your guinea pig than grass, hay is a cut and dried grass for consumption purposes for small animals. Grass may not have all the health benefits of hay in its natural form. 
  • Guinea pigs should start off with small amounts of grass/hay for the first time, this will commonly be done by giving them a small handful of the plant to see how they react to it. By doing this you can see if your guinea pig has a negative reaction to the grass and also see if they enjoy it or not in terms of flavor and texture. 
  • When feeding fresh grass to your guinea pig, be sure it is thoroughly washed and clean to prevent the consumption of bugs, and pesticides.
