From ignoring every toy to rolling on the rug
You've bought the wand, the mice, the crinkle balls. The cat looks at them once and goes back to sleep. And if catnip does nothing in your house, you're not alone — about a third of cats don't respond to it at all.
Silvervine is a different plant with different scent compounds, and most cats react to it. Hand over the stick and you usually get a few minutes of licking, rubbing, kicking and zoomies, then a very relaxed cat.
Four plant materials, nothing else
Silvervine wood for chewing, sisal rope for grip and texture, raffia grass at both ends for the crinkle, and a dried gall fruit for the scent. No plastic eyes, no bell, no stuffing to pull out.
Because it's real plant material, every stick looks slightly different. Watch your cat while they chew, and throw the stick out once the rope unravels, the wood splits, or it gets small enough to swallow.
