Rest in peace Brown
We were able to find this little guy. He was taken to the clinic. The skin stuck to the bones arrived in a horrible state, a huge tumor around the anus quite painful according to the doctor, kidney failure.
It was no longer possible to do much for him, just reassure him, make him feel good and let him fly with his own wings to infinity, away from the street where he lived since his old owner died.
We are sorry that we were too late in your life, we would have liked to do more. Have a good trip, little one. You will no longer be hungry, or cold, nor will you sleep wet with your empty belly. Now everything will be fine.
