My sister "donated" 3 hermit crabs to us; she had them for 2 months and couldn't have looked happier as we drove away with 3 hermit crabs in the car. Why? Because caring for them is so much work - as described in "Hermit Crabs for Dummies". I am constantly checking on them and poking them to see if they are alive. This is ridiculous, I don't have time for this!
