How can I make a Devon Rex stop jumping onto shelves with fragile items?

I once had a Devon Rex named Jasper who treated my tallest bookshelf like his personal launchpad. After losing a ceramic vase to his acrobatics, I realized he wasn't being naughty - he just needed a higher, safer alternative. I installed a wall-mounted cat shelf near the ceiling, far from the fragile shelf, and placed his favorite crinkly toy up there. Every time he eyed the fragile shelf, I'd redirect him to his new spot with a treat. Within a week, he forgot the old shelf existed, and my remaining decorations survived.

Redirect that energy to something they can dominate. I put a cat tree right next to my shelf and covered the fragile items with double-sided tape for a few weeks. The tape annoyed him enough to associate the shelf with unpleasantness, while the tree became his new throne. He chose the tree every time after that.

The key is understanding that a Devon Rex isn't trying to be destructive - they're just driven by an insatiable need to explore the highest point in the room. I've found that putting up clear acrylic shelf guards that are angled slightly outward works like magic; they create an invisible barrier that feels unstable under their paws. Pair that with a heated cat bed on a high, stable shelf elsewhere, and your little acrobat will choose the cozy spot over the tippy, uncertain one every time.
