FEANDREA Cat Tree, Small Cat Tower, Condo, Scratching Post, Light Gray UPCT59W

Is the sissle scratching post available to buy separate?

Is it possible to leave off the little hammock thing that sticks out? (Won't fit in my space if that is on it) thank you!

Will this fit 11 or 12 pound cats?

How much weight can that hanging basket withstand?
