Now to practice ...
Generally, the cage beautiful to look at and the flap toward the opening (above) is a good size and has good ventilation. More positive there is not.
The flap front for opening unfortunately makes free and would - if it would be possible because - again give a star deduction. The holes provide a good clue to munch on for the hamster. The bedding fills me up just below the two holes, so that my crumb has at least a little buddelspass. This leads naturally to the fact that the door can not be opened. Since the flap is not 100% on the housing rests nevertheless imposes itself often times a little litter from the cage out. Even if one takes very little litter (so no is the hamster but done like), you can see the flap poorly opened since the urging litter directly into the door opening and this in turn causes that can be the door no longer close ,
Last but not least were with me (as well as in other reviews read here) holes drilled wrong. This led 1. For this purpose, that a brand that was intended to fix the soil, now sticking out from the ground and has damaged the first floor rooms. 2. A plane could not be mounted because the holes were drilled too high.
Another mistake is that wood is not impregnated, and thus the entire urine may soak into the wood.
Conclusion: People who have no idea of the hamster attitude, neither should a cage for this build, sell! HANDS OFF!
