Got the aviary for my three rats bought! What can be so difficult without guidance on assembling the cage, but is a mystery to me !!!!! The joining of the parts can be explained but already on the basis of the form of self! The parts were slightly warped and the holes is not exactly - but with a little skill and no problem well worth the effort. The doors can still open and close quite strict, but better strict than too loose! Assembled and with the corresponding rat equitable interior is a true ornament of the cage and I can only recommend. Delivered I get him in no fewer than 2 days and to Austria! Great job - thank you!
