I once had a dwarf Siberian hamster that looked very much like the one pictured above. I got him when I was about 13 and he passed when I was 14. It seemed like a lot longer of a time but for almost 2 years I loved that little guy!
He had an amazing little tube home as well that was pretty fun to put together. I loved his little wattle too when he tried to run away if my sister and I had him out to play. R.I.P. Chilly Willy!
