Review on Habitrail 62690 Ovo Tower by Lisa Wilson

Bought the Habitrail Tower and Studio sets. I don't know how it makes sense since the same company makes the same products and individual elements, but the tower fits together much better than the studio. It's much easier to just connect the curves and bends. I agree with everyone else that there is not enough ventilation in the cave. So I took a nail, heated it over a gas torch and made some bigger holes. Then I scraped off the excess plastic with a knife. It took me about 5-10 minutes to finish. I would give this product 5 stars if I didn't have to change it. The photos show our Ferplast cage with most studio and tower sets. We have them horizontally because they are for Syrian hamsters and our Winter White cannot climb those wide vertical tubes.
