Satine was my first pet rat, rescued from a lab. She was already 2 and had never been socialized, and was quite antisocial for the frist six months I had her. When I got her a friend, she was so happy and so much friendlier. They would snuggle together and plan ways to steal chocolate and Ritz crackers... Satine became very sweet in her old age. She lived beyond her life expectancy and enjoyed half of her life in a loving home. I am content knowing that she is now scampering with Lady Margaret, her best friend, again. Big personality in a short little life.
