Water

Like the rest of us, cavies need to drink water. There are two basic ways to get water to your cavy:
Dish- I don't recommend giving cavies water in a dish. The dish will become filled with bedding and waste. Plus, it's just a big mess and a hassle.
Water Bottle- Available at any pet store, a water bottle is your best bet. It's a clean, easy way to give your piggers water. It's easy to clean and fill up and is mounted to the side of your cavy's home.

A guinea pig's water should be refilled daily. Especially on hot, humid days.
