This is certainly relative. My cat knows what things are his(toys) and knows to leave stuff that isn't his(not given to him by me) alone for the most part. No bite marks on my planes either. I was working on my SSE on the floor. He'd come up and sit by it and just watch even when I was out of the room.

He's an indoor only cat as well. Wife and I got him from a shelter when he was roughly five months old. Was neutered at the shelter early enough so he never sprayed a single thing in our house. Declawed his front paws as well which has worked out well - no claw marks on any furniture. This item helped when we first brought him home and we were working to break him to keep him off a few counters(cats don't have any place on kitchen counters where food is prepared).



There were a few times when this thing went off in the middle of the night when I had it set up on the kitchen counter. Laying in bed, I'd grin and think to myself, "Gotcha! Gotta stay off the counters, little buddy."

Just like a dog, if you're black and white about what they can and can't do and you're consistent it pays off.
