These are my first 2 rats, I will be getting another female called "Natasha" soon. They are the sweetest little things. I did get them from a petshop, but our petsmart seems to take VERY good care of their rats. These were friendly right out of the gate for me. They are a bit squeamish when I pick them up, but I'm working on trust training with them a bit, but for the most part they are friendly nice and VERY intelligent. I love them so much, and it's only day one!
