I just got some new food recently. They are Mazuri 5663 lab blocks. Below are some articles regarding lab blocks, which are rare in singapore.
Lab Blocks are said to be a good food for hamsters, as they help grind down the hamsters teeth, and also give a hamster complete nutrition as it does not allow choosing of the most tasty bits, resulting in an unbalanced diet.
Mazuri Lab Block Pellets are also for sale at $8.50 for 500gm (limited stock) for those interested in trying. Below is their nutritional content. - Sold www.mazuri.com/PDF/5663.pdf
