Thank you Julie, Candy, and Kat(by phone) for your kind words. I think I'm just about cried out now, although I still reserve the right to become weepy without notice for a while.
Boomie had another grand mal seizure early Saturday morning, and soon after that, we started him on another medication which left him unable to walk or even to sit up. And he was still having little seizures every few minutes. For a while, I wondered if the side effects might diminish after a few days, leaving him a little more functional. But how long might that take, and how long until the next big seizure broke through? By Saturday night, I knew that Boomie was not going to get better. My family didn't agree right away, but on Sunday I told them to really look at him. I called the vet's office and made the appointment to bring Boomie in on Monday.
I didn't give him his meds that morning. I was willing to risk another big seizure for the chance to have him a little more "alive" before we said goodbye. But even without the drugs, (and he didn't have another seizure,) I knew he was ready. And I was too. But as the doctor injected the euthanasia drugs, and I sat holding his head and petting him, I wasn't prepared for how fast he would slip away.
In spite of my grief, I feel relief that Boomie is no longer suffering, and he had only a few really bad days at the end. He had a good life up until then, beating the odds for cancer survival, and even growing old, as a beloved pet should. And for that, I feel grateful, even satisfied. I could not have asked for anything more from him.
I have been going through all my pictures of Boomie, and will probably post some soon.
