My sister has a teddy bear/golden hamster who is very sweet, and we were using aspen bedding, but we changed because he was coughing. We swichted to care fresh (not colored) because that is what they were using for him in the pet store. Is this the right bedding? And he climbs the bars of the cage then falls back down. Is this normal, for we have a two floored cage, would a one floored cage be better? 8-[ My sister got her first hamster the other day, but it died the next. Was it because we used aspen bedding, for that is what we used for him? Was it because he was handled to much? But we got her a new one (his name is TEDDY) and were using care fresh now. All replys are helpful.
