If your cat leisurely strolls across counter tops against your will, there’s usually not a single thing you can do about it other than let your cat do what it wants. However, there’s a possible solution called the CatNani Robot Guard.
CatNani detects whenever a cat jumps on a counter. Then it emits an ultrasonic warning and a harmless citronella spray to discourage the cat from walking across the counter top again.
Of course, most cats will probably swat the CatNani off the counter and on to the floor, but until that happens, you might consider getting a robot to guard your counter tops from your cat. Then again, a simple solution is to just get rid of all your furniture altogether.
