Brand new furniture becomes trash in months. Gotta mop up streaks when she decides to hide behind the couch and not drink her water. Get woke up in the middle of the night when fatty decides she didn’t eat enough.
I could sit here and type for a hundred years and not even come close to airing out my frustration. :p
God help me.
Put scratching posts (both vertical and flat) near the areas where they are doing this. Redirect when you see them doing it in the wrong spots, and you can get sprays to make certain areas more/less attractive for scratching. They also might want more play time. Scratching is normal cat behaviour but there are ways to give them healthy ways to practice it.
If you're buying one with rope, buy one winded vertical and one with horizontal winding. Mine hates the horizontal ones, but then absolutely loves vertical windings.
