Monza reaches 162 cm on a 48 × 42 cm base, with six levels and five open platforms. It is a tower built for movement rather than for hiding: most of its surfaces are places to stand, step and jump from.
Springboard platforms
The intermediate boards are mounted to flex slightly rather than sitting rigid, which gives a cat something back when it launches. It is the reason cats keep using the same route up and down instead of settling on one level and staying there.
A bolstered perch at the top
Around 30 cm across with a raised edge, so a sleeping cat has something to lean into. Below, two upper platforms of roughly 40 cm each and a smaller one of about 24 cm, plus a central open board.
Two caves and a bowl hammock
The upper cave measures roughly 32 × 32 cm externally, and the bowl hammock about 32 cm across — bowl-shaped rather than flat, so it cradles a cat instead of stretching taut. Two furballs hang from the frame.
