I agree with what everyone has already told you! I will add though, you took an alone, abandoned, scared, sick, old rat out of a situation no rat should be in. You made sure she had the warmth of hammocks, a home, places to snuggles, good food, and most important - you made her feel loved and wanted. You made sure she passed surrounded by love and not alone. Perhaps her brief time with you was all that was needed for her. As I see it, she created a new rat parent, that in her memory will continue to rescue more rats in need and show them the love she received, if only for a week. She did not leave this world in vain she had a purpose and you will remember her everytime you look in that cage once its full again. RIP sweet girl !
