Louse... the quality of the cat tree I have is pretty good. My 2 kittens are always ripping up and down that tree chasing each other, and they sharpen their claws on it all the time too. I've had it for about 6 months, and it's still in great shape, just like the day I bought it.. even after all of it's use.... so it was worth the 30 bucks I spent on it.
It doesn't actually mount to the ceiling... it's got a spring type thing that goes into the top of the tree... once you stand the cat tree up towards the ceiling... the spring thing with the rubber tip comes up and grips the ceiling to hold the tree in place... no screws or nothing go into the ceiling... it's real sturdy too, mine hasn't moved since I put it up.
That pic you have of your kitten on your profile is adorable.... soooo cute!!! Also the ones of Zero in the plastic bag... LOL so cute, my kittens love to do that too!
