This Mighty Cat Tower is unusual in that it wraps around a corner with an unusual footprint to make it less obtrusive. What a great idea! You probably should anchor it to the wall, but if the base is heavy enough maybe it wouldn’t need it.
The post is short on instructions, but has a good list of materials. And there’s a video to teach your kitties how to make the most of their cat tower. Check out previous posts on building:
Stumped by the cost of upscale cat trees? Judy DePasse of DePurrs Persians has some great instructions on building your own. It includes tools and supplies needed, dimensions, and instructions.
It took her less than a day to build using mostly materials you can find at Home Depot or the like. Be sure you use sisal that doesn’t reek of oil, kerosene, etc. You probably won’t find that in most hardware stores. The stuff I’ve seen at Home Depot was too heavily oiled.
