Assembling your Sky Citadel can take as little as 12 minutes. First, locate all 38 parts. Second, locate the one part that has gone missing. Third, find it inside the cat.
Once the parts are accounted for, simply attach Platform A to Pole B using the supplied bolt C, which fits through hole D, unless it is the other hole. If in doubt, our assembly hotline is staffed from 10 to 4 by Fenwick, who is not an engineer but is very reassuring. Please remember that the cat will want to help, and that this is how the screws go missing.
