It looks great, it's sturdy, it could be a wonderful cage EXCEPT that the plastic stinks so bad when the rats pee (we have two rats), and there is no side to hold in bedding so I cannot cover the floor with material to cut down the stench.  By the second day after cleaning, the cage gives off an odor that makes my nose burn. Plus the rats are already chewing the corner of the plastic, I am guessing I will have to replace the liner every few months.
