1. Not hidden!

It's not spelled "camelflage."
2. No.

3. Nyuh-uh.

I'm beginning to think "outfox" may be a misnomer.
4. Nada.

So classic, yet so obvious.
5. Awwwwwwwwwwwww but no. I can see you.

But you know what? I'm so glad I can, you fuzzy little num-num.
6. Nope.

7. Not at all.

But a great visual in case you need to explain the intelligence of a dog to anyone.
8. No and also, dangerous.

You's about to get STOMPED.
9. No(se)

10. Nooooooooooooooope.

I really like the audacity of both cats for staring straight at the camera, though.
11. Nah.

He has acres of long, tall grass behind him and he picks a tree to hide behind. Go figure.
12. Non.

This most traditional of disguises has failed you, squirrel. Hope you can get back your $200 for those Wayfarers.
13. Sorry, no.

But I am going to get this otter in touch with the bunny from #5 so they play the absolute cutest game of hide and seek in the history of the world.
14. Nyet.

15. And finally...not bad, actually!

This kitten may be young, but with good tonal matching between the fur and surrounding habitat, it shows hiding-skill promise. Just gotta get those typical cat straight-to-camera eyes in check.
