A couple of mine took a liking to a new sofa bed I got last xmas. They do the lower arm rest uprights. I've got 2 lg.sisal scratching posts and a bunch of angelical cat condos with carpet and sisal on the uprights. Anything out there that can be sprayed on area to deter them and is long lasting?
Was thinking of hot pepper spray. Stuff I see on the web doesn't look promising.

Appreciate any formulas that's tried and true. The sofa covering is holding up well, but I'd like to nip this now if possible.

Thanks,

Mike
