One of the endearing things about rats is that sometimes, when you're offering them a treat, they stretch out to take it, and with their mouth open, just millimetres from the yogurt drop or whatever, they pause and look at you sideways, as if to say, What's in this for you? Cats tend to be all Of course you adore me, while dogs are more Of course I adore you, but rats sometimes stop and wonder what's really going on. You can't say that's not very lovable.
