Yeah, this is a good video. It also reminds me that playing with my cats has taught me more about two very specific things related to fishing than I think I could have easily gotten to see any other way:
Cats, like many domesticated predators, play at a 1:1 mimic of the same behavior they would exhibit when they are hunting prey in the outdoors. They lie in wait and ambush the toy. The only time they bother to chase is when it's close enough that they feel like their odds of running it down and capturing it are very good.
It's helped me to better visualize just how much a lure moves when I manipulate the rod. For me, this is far and away the most important takeaway.
So what I do is tie one of their toy mice onto a light spinning setup, and I practice different pitching and flipping methods with them -- from classic pitching and flipping to dock shooting where you use the rod like a slingshot and all that stuff. Early in a session they're amped up for it so all I've gotta do is hold on. Once they're tired, however, it takes a little more work to get them interested. So I drag and/or hop the toy past them on the retrieve just like one might do with any number of bottom-contact lures. It's really interesting to watch them try to assess whether they can get it and whether it's worth the effort when they're already tired from playing earlier.
The dog tried to play once, but Morrigan, my teacup panther and 100% the house alpha, pretty quickly convinced him that isn't a great idea.
