anyone ever tried kingworms?

so, I went and got some crickets yesterday which the guys love (I made the mistake of leaving the bag with them in it alone briefly, only for the poor occupants being kicked around like crazy) and which serve as snack and kitty tv. The reptile shop where I get them also newly carries the kingworms, apparently a kind of giant mealworm. My research says they are incredibly nutritious (no, won't eat them myself, not even roasted) and, more important, quite lively. The Rogue did snarf up mealworms in the past, so I'll have at least one customer. Just asking out there: has anyone tried them out yet on a cat? Did it suffer terribly or only briefly (the worm. Not the cat.)?

Sorry late to seeing this but thought I would bump it up. Never have given Kingworms or mealworms to my kitties!!! Let's see of someone else answers this one.

if you haven't, definitely try crickets. Most cats can't resist a crawling, hopping cricket (Rascal is one exception, goes for decent-sized prey only)... the one trouble I have with crickets is that the Rogue, in his enthusiasm, will accidentally sit on them with all his 20 pounds which, 1., makes them stop moving and 2., effectively hides them from him. So this is less than ideal, but if possible I watch and point them out. 

I did buy two single kingworms (couldn't resist), threw them in with the crickets and now can't find them  (that is, without disturbing the poor crickets that act as kitty TV when I'm at work).

ahem. Experiment failed. The really nice and wriggly kingworm fascinated three subjects for 5 minutes and took a lot of abuse. However, unlike ordinary mealworms, it wasn't gobbled up after two sniffs... it got wounded but didn't stop wriggling. Then everyone lost interest for no reason . I put it outside to see if the ferals living on my porch would eat it, but they didn't. It ended up being bird food.
