Yes, we do (see http://fr.wikipedia.org/wiki/Hamster).

If you hamster isn't eating then it means it's ill. Take it to the vet and say that your hamster isn't eating.

Professor Layton Hamster puzzle, make Hamster walk 30 steps.

Please see the related link below for a walkthrough of the puzzle.

The symptoms that a hamster may have bladder stones are tiny drops of bloody urine which may leak from the hamster. The hamster will be in pain especially when urinating and the hamster will begin to look unwell. Offering dandelion leaves may encourage increased urine production so that the bladder stones come out. Dandelion leaves may be obtained from a gardener or a greengrocer.

An alternative is adding low levels of table salt to the water or food. Addition of a little fruit juice to salted water may improve palatability to increase consumption. You can also give some vegetables and some soaked food to your hamster. Extra Vitamin C added to the hamster's food will help in reducing the hamster's bladder stones.
