I'm not worried if they do sleep on it. This is more a lol darn cats post.
Mine view anything on a table a free for all to shove off it. Thankfully they don't mess with counters. We have a flat top stove now so I trained them to stay off the counters and stove when we moved. I think since we rarely eat at our kitchen table they are just like whatever the humans don't use it so we will lol. But when we do use the table I always give it a wipe down with Clorox or Lysol wipes. Having a toddler those are a must in my house. Lol.
Keeping cats off the table is like keeping my daughter out of my scrap basket. Impossible lol. My daughter views the scrap basket as her personal free for all. Every night without fail I am doing a floor clean up from her dancing and throwing scraps in the air. Very cute to see.
