What are Oreos made of?

Oreos are made of flour, sugar, hydrogenated palm kernel oil (a trans-fat), high fructose corn syrup, cocoa processed with alkali, and contains emulsifiers for baking. Oreo cookies also include eggs which can be a big problem if your hamster has allergies to egg proteins or is on an allergen-free diet.

The ingredients in the original recipe meant that they were vegan and gluten-free; however, it was changed in 2015 when the company introduced these changes due to pressure from consumers who wanted more “traditional” flavors like Double Stuf Oreos.

Why can’t hamsters eat Oreos?

Many owners found that hamsters can’t eat Oreos because they are allergic to chocolate. Hamsters should avoid all kinds of chocolate (including cocoa) as it can be fatal for them.

Hamsters cannot digest the sugar in an Oreo cookie and get very sick from eating one. The milk or cream in a slice is too thick for their small intestines to process quickly enough before bacteria grows and causes severe infection.

Plus, the high-fat content will lead to obesity which could shorten their lifespan by up to two years!

Because of these reasons, you want your hamster friend to have fresh vegetables instead of processed foods like Oreos! These healthier options may not taste good, but they are better for the hamster.
