4. I wouldn't feed the brand that people have been suggesting you feed so far on here. It has seeds in it, which are potentially deadly to hamsters. In fact, the mixes that are most common can cause type 2 diabetes in dwarf hamsters. In a nutshell, the reason is because of the amount of sugar added to the mixes such as Hazel/Harry, Kaytee (they're all the same, pretty much, a mix is a mix), this badly affects tiny dwarves, not to mention the fact that they will likely pick out the good stuff (sunflower seeds, peanuts) that can make them obese easily. The mixes are just as bad for syrians, although they typically don't get diabetes, they still might end up nutrient deficient, or overweight. Or, if they remain perfectly fine, they simply might not live as long as they can. I had a syrian hamster who lived for three years. I started him on a mix until I learned about Oxbow's Healthy Handfuls Hamster food. Its in a round o-shape, is 100% all natural, and corn-free. Its seed free, and all shapes are as uniform as possible, so the hamster cannot pick and choose.
Thats not at all true. A very large part of a hamster's diet is seeds,nuts, and grains, it is their staple diet. Yes, they're fattening but if done right (like not giving them tons of sunflower seeds and peanuts) they shouldn't be obese. I've had 12 hamsters in all in my life and I've never had an obese one.
This link is to a homemade mix for hamsters.. notice that the ingredients are seeds, nuts,and grains. (broken link removed)
Also ONLY RCs (russian campbells) and hybrids (which is a cross between a RC and winter white) are prone to diabetes.
