Hamster Food Consumption Calculator

How Much Food Does A Hamster Eat?

Hamsters eat an average of 11 grams of food per 100 g in body weight per day. This average does vary significantly depending on the species. Recorded averages can be anywhere from 10-12g.

However, because the calculations are per 100g of body weight, the formula works for large hamster breeds like the Syrian and Chinese hamsters as well as dwarf hamsters like the Roborovski and Winter White.

The point of the calculator is to educate hamster owners in order to prevent overeating and obesity that can lead to hamster health issues and a shorter lifespan for your furry friend.

Frequently Asked Questions

Why should I believe the calculator?

We use the average of several scientific studies that included hamster food consumption and energy requirements data. These studies include Arrington et al. (1979), Banta et al. (1975), and Birt and Conrad (1981).

Our calculator uses an average that is not gender or species specific.
