Guci and Prada come out to play!

I live in Asia and still get Rotastak through Ebay. It is also cheaper, as pieces are second-hand, but stil good condition.
When you handle your hamster, does she bite? Try feeding her from your hand, gradually increasing the amount of contact until you can feed her, sitting in your hand. If you can find a treat that she REALLY, REALLY likes, that will hep keep her distracted from sinking her teeth into your flesh. I've had Campbell's dwarfs who were like this in the past...Not fun! LOL!

When ever I put my hand near her she eats it like a shark, what part of asia are you from>

I had a hamster like that, too...I called her 'The Rottweiler'! She had babies and then sudenly became so docile. I guess motherhood tamed her! I live in Singapore, in South East Asia.

I live in Argentina and also have purchased rotastak items at Ebay UK, and they ship Royalmail Airmail. The problem is I want the kidney shaped one, but it's too large to ship. So the only options are Parcelforce or another courier, that charges a lot (of hidden charges also). Another thing, your hamster like the attic? My hamster don't like it at all, they never use it.

Does crittertrail fit to habitrail, or rotastak fit to habitrail or crittertrail?

I don't know about Crittertrail to Habitrail, tho I've heard you can fit the two brands together. I can fit together my Rotastak and Habitrail, using the curly, hard-plastic tubes from Rotastak and the special locking-rings that now come with Habitrail. Take a look at my videos section; I've got an instructional vid on how to do this.
