That would be Ember trying to find somewhere warm. Fortunately, I think it would be pretty difficult for them to turn the knobs by accident.When we had a gas stove with the pilot light in the center covered panel between the burners (two burners on either side of the panel) one of our cats spent cold afternoons sleeping on the panel. I had held each one up two feet back from the stove and turned on a burner to show them - fire! They got it. I still took the on/off knobs off the stove - burners and oven - every time I left the house and when I went to sleep. No point in tempting fate.
It's definitely proven to be futile, but I can't let him jump up there while the stove is on either. I'm still afraid showing them the heat would backfire. We let the house get pretty cool in the winter and Ember has a bit of an obsession with warmth. I've felt her get pretty hot before and she still didn't move. Cool water in a pot is something I'll have to keep in mind though.I think they probably mean magnetic babyproofing locks.
I don't try to keep cats off the counters. They far outnumber me so it would just be an exercise in futility . My cats don't jump up there while I'm cooking---if they get close I hold them near the heat for a few seconds until they decide not to get any closer. One burned himself jumping on a hot burner after I was done, so now I put a few inches of cool water in a pot and put that on top of the burner when I'm done to absorb the extra heat. That's not a problem if you have a gas stove.
The knobs are on the back of the stove, so the cats can't hit them when jumping up. Plus they have to be pushed down at the same time they're turned, so that makes it a little harder.They kick the knob on when they are climbing or leaping onto the stove. It's bad and worse if you're not home when it happens.
