If its the wood you might be able to sink a woodscrew into a post section. Drive it most of the way with a drill, and tighten the rest by hand. Make sure it goes in all the way so nobody gets their claws caught on it

See, the posts seem to be made of cardboard, so I think they're just weakening from being moved and living through the house fire. It was given to us by someone who's cat ran away, so it was already preowned. I was thinking about getting a 2x4 and anchoring it in the wood platforms from bottom to top and putting something heavy in the base just for support and balance

Hmm I'm not sure how to fix it then. I bet it would stiffen up a lot if it was screwed to the wall, even with just drywall anchors

Yeah, but we have a month to month rental, so I don't think that's an option
