Peppermint potted on kitchen window seal - Stripped of leaves over night

What on earth could have stripped my peppermint cutting? Any ideas please?

This was potted and on my kitchen window seal ready to plant outside. I went to water it this morning and it has been completely stripped of it's leaves. I have no pets and no idea what could have been at them. Whatever it is, it has shown no interest in the umbrella tree and Chinese evergreen which are currently sitting on the same ledge.

Any sign of catterpillar poo?

 

Thanks Scrungee. I didn't spot anything but I'll check for this properly when I get home

 

It's got to be a caterpillar or a snail. One leaves black poo, as Scrungee said. The other leaves silvery trails. Happy hunting!

 

It's so annoying when that happens, isn't it?

Whether you find silver trails, or black poo, I think my response would be the same.

1. Check the plant, soil, pot for any signs of aforementioned critters, and if found, remove

2. Plant your mint outside (checking around the rootball for more critters, as you do so).

Both potential culprits have no predators in your kitchen, apart from you. They have lots of predators outside!
