Who Should Buy Guinea Pig Food
When you first buy a guinea pig, you’ll need to pick out which food you think is the best for your pet. Often, many pet owners choose to continue feeding whatever brand of food that their guinea pig is used to eating. This may be easier on their pet’s stomach, at least in the beginning.
After your guinea pig turns six months old, it might be time to re-evaluate your pet food options again. Older guinea pigs need fewer calories, grams of protein, and calcium. If you currently feed your older guinea pig a food for young guinea pigs, his nutritional needs may not be met.
If your child has a guinea pig or your child has a guinea pig as a classroom pet, you may end up purchasing guinea pig food for someone else. Make sure to check with the guinea pig’s owner to confirm what the guinea pig is eating.
Important Features to Consider
Guinea pig food should have several important features. Here’s what to consider when picking out guinea pig food:
- Ingredients. Different guinea pig foods are formulated with varying ingredients. You want to choose a guinea pig food with high-quality ingredients that offer a lot of nutrition to your pet.
- Age-related blends. Since your pet’s nutritional needs change as he ages, it’s important to choose a guinea pig food that meets your guinea pigs current needs.
- Chemical-free. Ideally, any guinea pig food, pellet or hay you buy won’t have any chemicals in any of its ingredients.
- Hand-selected ingredients. Some guinea pig food brands boast that their ingredients are hand-selected. This can ensure that your food is made from the highest quality ingredients.
- Size of bag. Many guinea pig food bags come as a 1, 5, or 10 pound bag. While a lighter bag is easier to maneuver, you’ll have to buy larger bags of foods less often.
- Artificial flavors. If you read the label carefully, you can often find guinea pig food that is free of artificial flavors and/or preservatives.
