I used to have a hamster a long time ago, and these are the items from that time. m(_ _)m After it passed away, I washed everything and stored it in the storage room. Since I don't plan to use them anymore, I'm hoping someone can make use of them. m(_ _)m Cage size: Width: 38 cm Depth: 25 cm Height: 23 cm So it's a manageable size. The heater has some rubber missing near the cord, possibly because it was chewed on. It seems like some repair is needed, but it does have a guard. I plugged it in to test it, and it got warm, so it seems like it could still be used if repaired. The food dish is different from the one that came with the set. Also, I can't find the part to secure the water bottle, so please be aware of that. m(_ _)m These are also sold separately, so if you get one of those, and just buy some wood shavings, you should be able to start raising a hamster right away. ^_^ I washed and dried everything thoroughly after use, and stored it, so it's generally clean, but please understand that there is some aging.
