Why should you start your own guinea pig garden?

There are plenty of benefits to starting your own guinea pig garden. Here’s 4 good reasons to help you make the decision:

Fresh tasty vegetables conveniently at home

You start to hear the hungry wheeks calling out to you. Your guinea pigs remind you that it’s dinner time, so you quickly proceed to the kitchen to start prepping their meal. You open the fridge and find that someone has used up that bunch of lettuce you’ve been saving. If you had some vegetables ready from your garden, you could save a trip to the shop by picking some from your very own plants. Convenient right?

Help cut down on guinea pig food costs

Fresh vegetables are an important part of any guinea pig diet! In fact, each guinea pig needs approximately 50 grams of fresh veg per day. While that may not sound like a lot at first, that quickly adds up, especially if you have a large herd! By growing your own plants at home, you can help supplement your food shop with some tasty veggies or herbs you have right at home.

Good for the environment

Growing your own fruits and veggies is not only good for your guinea pigs but also good for the environment. Many fruits and vegetables are shipped out in plastic packaging which unfortunately contributes to the waste that we humans produce. By gardening, you are effectively cutting down on the need to purchase items that require the disposal of packaging.

It is found to be quite therapeutic for many individuals, not to mention the opportunity to catch some much needed vitamin D from being out in the sun! Gardening can be as involved as you’d like so it is a great hobby to pick up should you find yourself having a busier schedule.
