What do they do with dead zoo animals?

Autopsy. Then feed them to the other zoo animals who eat other animals. It's the circle of life!

I would bury them and have a little animal funeral and have all the animals there to pay their respect. Or take them to a taxidermist especially the bigger animals like giraffes or elephants. Or send them down a river and lay flowers on their body.

There are facilities were they cremate them.

Your welcome.

Been to McDonald's lately? Ain't those chicken nuggets good? Yum, yum.

Release them into the wild.

They serve them up at the concession stand.

Juice em for biofuel- my SUV runs on endangered species and the tears of children.

They dress up the dead zoo animals in high quality, diamond studded sailor outfits and they have a tea party. The tea isn't really tea though, it's actually expired apple juice from a can that was harvested out of the dumpster from the back of a supermarket.

They stuff them and bring them to my kingdom! I have tons of exotic birds
