FBS, so sorry to hear about your little dear one, I don't care if it is a cat, dog, horse, lamb, turtle, fish, mouse, rat, bird, or in your case a Gerbil, these are our little babies, to me all life is precious and we could learn a lot more about love by watching and taking lessons from our four legged , two legged, fur , fin, scales or feathered friends,

I hate to admit it, but I get along way better with almost all animals or any sort than I do with people, except very young children who haven't formed judgements yet, and older persons who know what it is to live and want some dignity and love at the end of their lives.
Anyway, your pictures of Susi and video are a loving tribute to your dear friend, Little rodents just don't live long by our standards, but they put a lot of energy and life into that time, It is a lovely video that I will watch over again when it is quiet in my house. You can never replace Susi, and you shouldn't , you can get another Pet, but each pet is an individual and has their own relationship with you as you do to them. Cherish the memories you have of her and the times you spend, even just watching your friend, I know from talking to you and reading your posts, that you are a very very caring individual and have a unique relationship and understanding of animals in general that many people,( even as an adult,)never acheive, so be proud that you are one of the few special people who can understand these special little creatures. Thank you for posting the pictures and video of your baby Susi.

It made me remember my little Rat, Cinderella who passed on years ago.
