One, if you play laser tag with your cat, make sure she “wins”. Because since there really is nothing for her to catch, it can frustrate the cat. I always give my cat a treat when she “catches” the dot.
And two, regarding the scratching post. I had the same problem. I suggest a carrot-and-stick approach. Put a small treat on the scratching post. And keep a squirt bottle of water handy. Give the cat a quick squirt when she tries to scratch anything inappropriate. Cats do learn fast.
Just be sure you clean that squirt bottle out first.
Squirt the cat when it scratches and don’t let it know it is you. The cat has to believe that it is a direct result of the scratching. Or....google ‘sticky paws’
