I'm not sure where Sierra first came from or even how old she is. The only information I have is she was dumped on a friend of mine by his roommate. Not long after the friend had to move so Sierra stayed with some people in their basement for several years without much attention.
This didn't seem to do anything to her personality though~! She's loving and very cuddly.
She enjoyed checking out her surroundings that first day and playing with some new toys, come bedtime was when she started to get upset. She would pace and meow at night for the next 3 days. I stayed up all night with her to try and calm her.
Now she is completely settled in to her new home and having a great time.
