Ahhhh, they are just precious!! I've always thought Siamese rats were gorgeous, and these boys are no exception. I imagine they will come out of their shell in no time, I remember my boys being just the same when I first brought them home.
They're beautiful! Nothing quite beats earning a little rat's trust does it? I'm so jealous, once my two boys are gone I won't be getting anymore for several years. I want more rat babies. I swear pet rats should be classed as an addictive substance.
