Our cats are very fussy and keep changing their minds as to what they will eat, so we often get leftover cat food which I put into the food waste bin - and then get maggots in this hot weather! I've tried washing it down the sink and got a blocked sink. And apparently the same thing can happen if you chuck it down the loo. No dog. And I really don't want to tie it up in a plastic bag when I'm trying to not use plastic! Any suggestions? Thanks
