Doh! And for my second wish... I'd like a can opener..... Doh! And my third wish is for hands. Too bad you blew it by turning the genie INTO the can of tuna instead of just wishing for a can of tuna, you stupid cat! That's a pretty raw deal for the genie. No wonder she looked so disgruntled in her last moments.
But it's a good joke. There's no reason legends of genies should be so human-centric, we're talking magic and cosmic forces that can shake the universe, and humans have a petty role in that universe. Unfortunately, you wouldn't expect what other species would do with that power to be all that rational. Though in my experience, I think cats would be better than that, they're not at all like people say, they definitely value companionship way more than food, they're usually very lonely creatures.
