Any problems you encountered?
Leaves build up on top netting. For multiple cat households consider TWO cat doors and TWO cat walks. Otherwise, territory issues ensue. Consider adding another catarium to another side of the house as well IF some indoor cats run off by others.
Also, don't force sharing of Catarium becuase territorial "pay back" by dominants may happen - as it did us.
