What Should I Feed My Rats?
Rats are an easy pet to own when it comes to food. There are only a few foods that rats can’t or shouldn’t eat. Otherwise, they eat just about whatever we eat. Rats are omnivore, meaning they will eat meats, fruits, and vegetables; however, they love their veggies. Items like green peas, kernel corn, and chopped carrots are too irresistible for most rats. Just like humans have a food pyramid, it’s easy to remember the proportions of what should comprise a rat’s diet: 80% lab block, 18% supplemental foods, and 2% treats.
While the below lists shouldn’t be considered exclusive lists, but they are fairly comprehensive. Again, rats are very flexible with their food choices. They don’t have a gag reflex and can’t burp. Therefore, they will be cautious at first with foods to which they haven’t had exposure. So, we will cover the foods they can’t or shouldn’t eat first, since once you know those foods, you can easily supplement your rats’ diet with just about anything else.
