Self-made cotton paper was a very important and necessary item when hamster breeding. It could be bought from the Internet. The product was whole, raw, pulp paper, without any artificial dyes, and it could be cut into finger-wide strips. Hamsters would instinctively search for nesting materials after giving birth to their pups. If they couldn't find them, they would be anxious, even if the owner had already made a nest for it. It was useless, however, as it would only be reassured if it was a nest made by the hamster themselves.
The cotton paper was given to the children for free by Zhang Zian––a pack was only ten yuan––and he had the children cut them into paper strips.
When the children saw that the female hamster was actually eating the cotton paper strips, they were all very shocked.
"Is the female hamster hungry? Why is it eating cotton paper?" Little Celery asked, worried.
