(picture from when I first got him!)
Rest in peace, little guy. You were just the friend I needed through those years. I love you.
You never ever let me be sad. You always knew when I was sad because you'd sit by your door and look at me until I went to pick you up. And you'd sit on my shoulder and lick my cheek or play with my necklace until I felt better.
I'm really glad you lived to be 4 years old without any sort of complication or struggle. I'm thrilled that you had a good life and went peacefully. I'm glad age took you and you didn't lose to an illness. I'm glad you proved everyone wrong when they said getting you was a bad idea because you were supposed to be a feeder rat. I'm glad you wouldn't ever bite anybody. I'm glad you were my first rat and I'm glad I got to have three amazing years loving you and caring for you. I couldn't have asked for a better friend.
Thank you for everything. Rest easy, my friend.
Mouse. Because that's what I called you all the time.
