I can imagine the AIBU
I am a feral cat and I visit a wonderful food bank, set up for me and my mates. We enjoy several pouches of Felix every day.
Recently a collection of cats who live with humans (and are therefore not in need) have started coming to the Cat Food Bank.
They eat everything in sight. Even pouches which I know they refuse when their owners buy them. They laugh about this. ("Ha ha she bought 96 Felix Cod AGAIL and I refuse to eat them at home. It really upsets her lol")
AIBU to report these cats to the authorities? They shouldn't be eating our food, the bastards.
