Jonna, in general, kitties will use, even prefer, their own scratching post, if you give them one. The easiest for me is a two/three foot piece of coconut tree trunk. It doesn't shed much or at all, and costs zip, if you're there when someone cuts down the tree. I guess any palm trunk would work. Or any tree, but a barky tree can get messy.
I guess the Thailand nurseries might all be out of business by now. So sad, the flooding. Most of the population lives on flat land, and the hills are wooded and sparsely built upon.
