Ware Manufacturing Home Sweet Home Sunseed Guinea Pig Cage Starter Kit - Durable & Spacious Small Animal Habitat for Indoor Use, Perfect for Guinea Pigs, Hamsters & Rabbits - Ideal for Pet Playpens, Bedrooms & Living Rooms

Let me start by saying that I have only one guinea pig (GP), and I think the space is enough. You will need to buy a small enclosure so that the GP can hide if it feels so. The cage is well made and sturdy enough. I cannot complain about the rest of the items, the bedding is good and the pellets are good (in fact, I am going to continue using the same brand in both cases). The GP ate the hay that came with the kit, but it is not the best, although the hay I have found in stores is not much better either. Buy instead the 'Small Pet Select' hay, your GP will dive in and devour it. Overall the kit is good as a start, I recommend it.
