I happened to find an Etsy seller, Fish On Flies, who makes very large lures for cats. He’ll make any of his flies without hooks for cats, and his prices are very reasonable.
They are also really, really beautiful little works of art. I’ve always been fascinated by fishing lures, especially flies. It’s just so amazing how humans try to outwit fish with scraps of fur and feathers, so primitive and yet also so technical.
But of course, the real question is, do cats like to play with them?
I’d have to say yes on that count.
