Query: wood is thin and carpet is super thin and cheap

Pros: -nice size, the one cat who uses it loves the height -not very expensive for the size -relatively easy to assemble, though you have to be careful that you don't screw any of the bolts all the way through! Cons: -the wood is thin and flimsy -the 'carpet' is SUPER thin and cheap and I'll be surprised if it lasts more than a month after my cats get used to this thing enough to start scratching it -Because it's so flimsy and tall, it wobbles when my cats jump onto it or are active while on it. Which makes them feel insecure and 2/3 of them won't touch it.
