It’s an online survey of cat owners, seems funded by that company that sells air fresheners for cats.
They found no connection to scratching and their product, but did find that cats in houses with kids scratch more.
So sell your kids and enjoy that scratch-free sofa.
We do only wet food. Our last cat needed it to keep up hydration, and now we do the same with our new cats. Def more expensive, and not sure it’s worth it for healthy cats that drink enough.
