i find it best not to eat it, but if you have a liking for a cat nibble, try twiglets instead
on a serious note, if its a cat problem, you might need to do a weekly poop a scoop check and just go round and get rid of the little land mines.
most cats are quite good at digging it in so some of it shouldn't be an issue.
my folks use a tiny water pistol to shoot it in their cats direction (usually when its eyeing up my dads fish)
maybe have a chat with someone at a pet store?
