Shipping took way longer than advertised by site!  Arrived nearly a full week later than advertised.  Instructions for assembly were not super clear.  Door opening for easy cleaning is adequate for my 8 year old to fit in.  The base and solid pieces for the base and tiers are thicker vinyl material, think tarp like so not sure how long they will hold up.  Overall I feel like it will serve it's purpose to keep our orphaned kitten safe from the rest of our zoo for now but not sure about it's long-term use with future rescues.
