Avoid newspapers and other printed paper as bedding because your hamster may consume the ink when they are tearing up the paper to make a nest. There have also been rising reports regarding the toxicity and dangers of cedar and pine shavings as bedding for hamster's cages. Some of the alleged health problems as a result of regular use include itchy skin and scratching, and even liver problems.
The use of fluffy/cellulose bedding, which has the appearance of fiberglass/cotton wool, is also suspected to cause choking, pouch infections and intestine blockages.
Although such claims lacked hard evidence, there had been some scientific studies and anecdotal evidence of the dangers of these bedding.
