I'm sorry to hear of the sudden loss of your Mirage... It's a great shock when they leave us so unexpectedly and still so young, you have my deepest sympathies.
Be sure to give some extra tlc to your Winter, I hope you will both feel better soon.
Time will heal the pain from not having your Mirage around and the memories of the good times you had with her will always be in your heart.
Rest in peace, beautiful Mirage. You were much loved and will be missed.
