Hi all, we are thinking about getting 2 guinea pigs for our young children, I have read the newbie info and found it very informative. The question I have is what type of hutch/cage to buy. I was thinking of a wooden two tier (living part upstairs and run underneath) but have read confusing reviews. Some say the wood is cheap and others say that the ramps are too steep for the animals to use, has anyone else had these issues? If not what brand of hutch is best quality/price. Secondly I noticed that some of you use the open topped metal cube type affair, do guinea pigs not climb out? (Sorry if it's a silly question). The reason I was looking at wooden rather than wire cage is because we plan to have it indoors during the winter and out during the summer months. Any advice greatly appreciated.
