My bunny

I have a bunny that I rescued 11 years ago from a local shelter. He was a stray found running loose. At some point he was someone's pet bunny as he is tame, friendly and loves people. I do not understand how people can just discard something that they once loved. It is very obvious a rabbit can not live on their own in the wild. They are lacking the proper skills and instincts not to mention the ability to blend in. I have had him for 11 long years and I love him very much. sadly he is getting older. He is unable to do the things he used to do. I am worried I will not have him much longer :( He has always been an amazing bunny and I adore him.
