I get this question ALL the time. I usually just get a big cheesy smile on my face and say "because I LOVE them", but I'll usually throw out the "well my landlord won't let me have cats or dogs, so I had to improvise", or "my son really loves them too!".....but to be honest I have no idea why. I really do love them, and it certainly is an addiction. They are just such interesting little critters, each one has such a different personality. I love mine to pieces![]()
