The Correct Diet Is Important

If you’re new to the world of hamsters, you might not know that a hamster’s natural diet consists of all kinds of interesting (and sometimes surprising!) things – these rugged little omnivores are capable of eating everything from crickets to amphibians!

We’re pretty sure that wild hamsters would never encounter an onion in their natural habitat, and it’s fairly safe to say that they’d give this strong-smelling plant a wide berth if they did happen to stumble upon it.

So, what else should your hamster eat?

• Hamster food, which is specifically formulated to satisfy your pet’s unique dietary needs. The package label will tell you how much to offer based on your pet’s size and life stage.
• Unlimited supply of fresh water. Remember to help your pet stay healthy by rinsing and refilling their drinking bottle at least once each day.
• Fresh hay and dry hamster bedding, which contribute to health and happiness. These essentials let your hamster engage in natural tunneling behavior while customizing their habitat with useful caches, little burrows, and of course, cozy nests.
• A little birdseed – Just a teaspoon per week adds a little bit of healthy fat to your hamster’s diet and gives them something that’s safe (and fun) to stash away for later. Hammies love to nibble, and they really like to build food caches.
• Tiny bits of fresh produce each day or once every other day. Give your hamster vegetables more often than you offer fruit, since too much sugar can cause health problems.
• Chewable treats and hamster toys designed to keep your hamster’s teeth from becoming overgrown, painful, and maybe even infected. Your pet needs something to nibble at all times.
