I have two of these boxes purchased at our five new entries (cats now has four months old, each 1.5 - 2 kg) to create sure the vet and back. Unfortunately, these boxes have some serious weaknesses: - Difficult assembly (quick-release fasteners are in separate parts at), detailed instruction is missing (has been criticized here several times and can be confirmed only by me) - Lateral quick-release fasteners very questionable; when assembling the second box already a broken (was also objected here many times and can be confirmed only by me) - Locks the upper grid untrustworthy - occupied by two small cats, or about 4 kilos, quite a bit of weight depends on these very lüttigen plastic Riegelchen. One of our old cat (6-8 kg) I would therefore not want to raise!
Conclusion: For 25 euros you hereby gets only half-baked Italian plastic crap. Unfortunately, common in this price range! Have the locks on the upper flap thrown away and sealed with cable ties. Now, the function of this flap is natural history, but the box is secured against chapping. Who can do without the top access, should therefore assume a priori a closed top and therefore more favorable transport box. I also have the half-shells of these boxes also tied with cable ties, if another quick release gives up the ghost. In sum of all defects and rework so I not advise !!!
