Goddammit, cats are obligate carnivores! Don't try to feed them bread, you dumb lesbian!
Just because they have to eat meat doesn't mean they can't process anything else. Cats can eat almost anything. They just cant survive on just everything like humans.
Of course cats have to eat meat doesn't mean it can't eat anything else. My cat loves bread :3 i have to lock my bread cabinet because my cat would try to steal my bread and sometimes their attempt to open it works... i wake up to crumbs everywhere.
Sure, it's not (usually) toxic and it's not as bad as if it were milk, but it does mess with their digestion for a net nutritional loss. Just because they can eat it doesn't mean they should.
