Marvin is doing great! He is getting around as well as he was before surgery to our amazement. As soon as my husband got home Friday evening Marvin got up and started walking around on his own! He's eating, drinking and going poop/pee just fine. My husband is happy now that we made the decision to get the amputation! I guess today is day 5 and things could not be better, incision looks great too. The look on his face is happiness, the way he looked before the big tumor came back. I did get some sleep over the weekend, finally. We go back Thursday for his 1 week check up. Thank you all so much for all your support and I will be sure and post updates on his progress.
