My cat is on my last nerves

[A_Nanny_Moose]

Have a large tuxedo cat, and despite having 2 entirely different scratching posts, he will scratch literally everything. My furniture, carpet, shoes, linoleum floor in the kitchen, the wall)(yes the corners And just the wall), doors, etc. I've tried squirt guns, chasing and yelling, throwing stuff, etc.
Declawing him is a last resort that's coming up quickly, and I don't want to cover my entire place in double sided tape. Can I get and use a training shock collar for those tiny annoying little dogs?
