I took the stray I had been feeding in to the vet today for an exam and disease check. Unfortunately, I discovered he had FIV. Because of the combination of FIV, his eye problem (he only had one functioning eye), his age (between 10 and 15 years), and the probability of hyperthyroidism, my vet and I decided it would be best to put him to sleep peacefully. He had been living in my apartment complex for at least a year, but I doubt he would have survived another winter. I know in my heart that giving him an easy passing was the best thing I could have done for him, hard as it was for me to watch him go. I put up flyers on everyone's door so that they can get their outdoor kitties tested too. I named him Diego on the way to the vet's office. Rest in peace, Diego. You will be missed.
