Nine: Canned Vegetables
A well balanced diet is essential for your pet rat to thrive and live a long and healthy life. As such, your pet rat should get plenty of carbohydrates, the right kinds of fruit, and a steady supply of vegetables. However, be aware that rats (like humans) will be a lot better off with fresh veggies rather than canned.
For one thing, canned vegetables often contain a good deal of sodium, which is unhealthy for rats. Sometimes these vegetables will contain corn syrup or sugar as well, which can lead to obesity in your pet rat.
