3. Most cats love it.
Catnip leaves and flowers can trigger chemicals in a cat’s brain. For that reason, dried catnip and catnip-laced toys make regular appearances on pet store shelves. Pinch the leaves first to release essential oils, and a little catnip goes a long way. You also can refresh old toys by placing them in a closed jar along with a catnip. It’s a great way to jump-start a fat cat’s exercise regimen.
