Oh yes, 2 vets got on the phone at different times and recommended this as the most humane thing for him. I trust them explicitly. I couldn't go see him. They said he was beginning to be very vocal (in pain), his body was not responding, and I didn't have the heart to see him in this condition. I don't handle situations like this very well. Unfortunatley my husband was out of town or he would've stayed with him till the end. I feel bad for my husband to find out this long distance. This happened so rapidly and the worse part is the unknown of what or why caused this. Our other 15 cats are just fine so the vets don't feel it was anything toxic, his blood work was perfect so they don't think it was anything contagious. Guess it will be something will never know. It's hard to lose a beloved animal friend and companion. Thank you all for your thoughts, prayers, and concern.
