I am learning from many pet owners, the loss of their pets are one of the hardest things they have remember. Pets depend their lives on you ... you control 100% of their lives and they never complain. When you loose them, you loose the most important things in your life and you will not get over.
You try to remember ... You do not want to forget ... After all, for your pet, you are everything to it. I try to keep the memories alive by drawing him.
