Really, how can I stop them from eating my plants? Some don't have leaves anymore. They are not even edible. They are even biting the cacti for some reason.
I put the plants out of reach and that only made them figure out new ways to reach higher furniture.
Not plants per se, but we had a problem with one of our cats jumping up in the kitchen counter. So we put a few coins in a coke can and then shook it furiously every time he jumped up. You have to watch them for a while, but it doesn’t take long for them to learn.
