Mark,
My most sincere sympathy goes out to you. Over the years I have had to put 3 cats down and it is a pain that cannot be described. There is, however, another way to look at this that might make you feel better. Our pets are members of our families, making this decision so very difficult. On the other hand, if this was a person you would be forced to watch them in pain to the bitter end with no chance of relieving their suffering. With our pets we do have the opportunity to close the book once they’ve lost the quality of life. It is a remarkable gift that we can give to our pets that we cannot give to our human family members. I hope this makes you feel better.
