Yesterday morning, I went out on the porch to feed my 15 year old kitty, Mew Mew, and he didn't come out of his house. I knew something was wrong because he normally waits by the door "attacks" his food as soon as soon as it hits the dish. I knelt down by his house and he was just sitting inside with his eyes closed. When I said his name and touched him he opened his eyes a bit and started purring. I noticed his breathing was very shallow and he was struggling to hold up his head. I knew that he was leaving me... So I sat with him in his favorite spot and petted him softly until he quitely and peacefully passed away... I will miss you, Mew Mew.
