All kittys jump on things and push over things. Its why we cat proof our houses. Just like we do for our children.
I bought some beautiful ceramic flowers and put them in a vase my aunt sent me that had been in the family. My cat wouldnt leave the flowers alone. They broke a couple. Tipped over the vase several times. Finally I put it all away. I was a lost cause and my kittys are my companions. We all give things up in this life for companions, kids, husbands, etc!
