I indirectly thank you, Rod, and here's why:
I didn't remember if "Wilko" was a brand name of beer or a store or both. So I go to the UK site (which was suspicious of my interest in it and so I had to pass tests to prove I was human--I am).
Now I'm on the store website, scan over the selection of beer kits (nice). Still curious about the store, I search "Cats" and find they sell toys. They have this wiggly fish that seems awesome.
Since I wouldn't have one shipped from there, I check around here for one and they do have it.
It would seem my cats will love it.
