My kittens love this tree! They're only 14 weeks old and already starting to outgrow the little cubbies and when they're in the top bed together it's a bit of a squeeze, so I'd say it's not suitable for multiple large cats. It's their favourite spot to nap, and they love scratching the surfaces and playing with the little toy too! It's really sturdy and well constructed, with clear instructions and extra parts. Took about 20 minutes to build and doesn't wobble at all. It also looks great in my apartment! We'll probably purchase another bigger tree from Tucker Murphy in the near future :)
