Building a cat tree is entirely possible if you’re handy.
If you’re looking to buy a cat tree and you’ve got a little short of money you’ve got a problem. If your cat is scratching the furniture and in need of some fun time then you’ve got another problem.
No money for a cat tree and a bored cat.
But there’s no reason you can’t build a cat tree yourself. Building a cat tree isn’t as hard as you think and it will save you some money, though of course you still need a little money for the materials unless you can scrounge well.
Here’s a good video showing you how to build your own cat tree.
