Base and height work together
Tall products need enough stability for the cat's weight and movement.
Placement matters
A stable product on a level surface is more useful than a tall unit in a cramped route.
Replace worn parts
Loose platforms, fasteners or heavily damaged posts should be repaired according to the manufacturer or retired.
Cat preferences vary
Some cats prefer height, enclosed spaces or horizontal surfaces more than others.
