AmberLV, I'm so sorry you're facing this. I was with my son in Feb when he had to have his cat PTS and with my sister last month when she had to have her pom PTS. It's gut wrenching, but in both cases it was the most humane thing to do because they were both suffering desperately.
I know how badly you're hurting and I wish there was an easy way to make it all better, but you must weigh this baby's quality of life against having him PTS. What a sad decision......my heart breaks for you.
