Cat toy for lazy humans (+ bonus) (Staple Hill BS16)

The fish is somehow movement/contact-activated and will flounder about when disturbed, givingyour cat hours of amusement with absolutelyno effort from you (except possibly to film it for TikTok... this could be how you finally go viral, kids!)
Happily, you do have some agency here, should you wish to exercise it... fishy - who takes one of those small disc batteries - has an on-off switch so you can cut off the fun at bedtime.
Oh. And there's a pocket thingy for some catnip. That could be handy when you decide to try out the bonus "steamy" (misty) brush on your exhausted moggy.
