You can see both the Coatimundi and the Cacomistle at the Stone Zoo.

Er, well, you can see the Cacomistle if you are lucky.

The Coatimundi is really adorable and suprisingly nimble/dextrous.
The Cacomistle is adorable, but we've only seen it once in all the times we'd been to the zoo. It mostly comes out at dawn or dusk.
