I talked to my mom this afternoon and she told me they had to put one of the cats down today. She found him this morning with a very sudden, very serious condition and they chose to not prolong his pain and suffering.
He had a hard life from the start. When I was living in Brooklyn, and had just gotten my dog Milo, we were on a walk and Milo kept pulling me toward this chainlink fence, so I went over to see what he was so captivated by. It was a tiny grey 6 week old kitten with an upper respiratory infection, and eyes crusted shut. Laying there on the sidewalk all alone. I knew that if I just walked away he would surely die. And luck would have it, I was going to visit my parents upstate that day. So I went home, found a box, and packed the tiny sick kitten up for a ride.
My mother, father, and sister took him in and nursed him back to health.
He had a very happy six years with my family. We're going to miss him.
