How long could a Zombie Apocalypse seriously last?

Realistically it will last until they rot. Which mean it will end by the end of Summertime for most regions, and for the more Northern regions it might take longer.

And then immortal penguin zombie kings rule Antarctica.

Well that's assuming they don't get eaten by wild animals.   I mean, walking free dead meat, since zombies generally only attack humans.  All the suddenly abandoned cats would probably go feral rather quickly and zombies would end up being their food of choice.

I don't think animals would eat rotten meat unless they're starving. Wouldn't be too hard for Zs to pick them up and take a bite either, seeing as they won't feel the biting and scratching from the kitties.
