My guinea pigs are loving it so far. But to be clear you have to order the top separate (that’s why I’m giving 4 stars instead of 5). The product specification when I bought said “Removable top: yes” which why I ordered from Wayfair instead of amazon. However, top does not come with it. My pigs are happy as can be right now, I just live in an apartment complex and want to have a top option when people come into the unit.
