I like the overall design.I have 4 cats that use it. they barely fit on or in it. It needs all the platforms and houses to be just a little bit bigger so the cat doesn't hang over the edges or overstuff every part on it.

Its easy to clean when they puke on it.
They haven't tore it up yet . It seems to be pretty well made.

Thelittle yarn balls were chewed off within minutes. Looked like a good idea just waste of time to even tie them on.

My cats are nomal size cats not huge.2 Hienz cats and 2 Manx.
