BBQ? fur coat? ha! j/k
hmm. i would get a shovel and a BIG garbage bag and some gloves. get someone to shovel the cat in the bag while you hold it open with your gloves on. then tie it nice and tight and put it in the garbage.
where i live, this wouldnt be a problem because at night, racoons, lynx, coyotes, bears or foxs will usualy eat any leftovers.
