Insane
Our cat goes absolutely mad for this thing, he doesn’t just play with it – he goes into full-on hunting mode like he’s after a real creature. He could chase it for hours on end if we let him. Definitely a 10/10 buy. But you do need to keep an eye on them while they’re playing, because if your cat likes to bite, chew, or carry toys in their mouth, the worm will lose some of its ‘fur’ and the cat might try to eat it. You can get replacement worms online, which is handy.
