HCA: Hermit Crab Association

Right when I got my first E he escaped. Then a year or so ago he escaped again and my cat brought him to me (my cat fetches, so she figured it was a toy) but don't worry he survived. Then just the other day I walk into my room and see a hermit crab crawling out of the smallest space that cracked in my lid. I caught him and put him back in. The next morning I walk out of my room and laying next to my two cats is a shell... I pick up the shell and it was a hermit crab! I can't figure out way a hermit crab would want to come out of their warm humid tank and explore a house that is freezing(to them) and not humid at all.....
Is there something I can add to their tank to make them not want to escape?

They are curious little creatures.

Mine seem to enjoy their tank, but that doesn't stop them from trying to find a way out every now and then. Besides, each one has a different personality and I think you may just have a little Houdini on your hands.

My suggestion is to find something to hold the lid down or he's gonna keep escaping.

So cute! I can't think of many ways, he seems pretty agile. Maybe he needs a beaker. Or a motion detector lolz

I suggest you get some tank clips. I like these: http://www.amazon.com/Aquarium-Tank-Sec ... 462&sr=8-2 They also come in a larger size for bigger tanks.
