The Deli Nature hamster food includes grains, fruit, nuts and animal proteins. Small rodents, such as the hamster, are naturally omnivores and therefore need animal proteins in addition to vegetable raw materials. Hamsters like to gnaw, which is why the Deli Nature Hamster Menu contains a range of treats, such as banana slices, archids, sunflower seeds, pumpkin seeds and carob. These treats are slightly larger so they can gnaw on them.
