and was out on my own. I've always had several at any given time and I've seen the mourning and sadness that happens when one passes. I remember this one white cat I rescued... one blue eye, one green eye, and no depth perception. He was a standoffish kind of cat... didn't really like to mingle with humans or animals. But he made a pal with another white cat I'd rescued. I held Toby in my arms the whole time he was dying. And that entire time, Skeeter (the other white cat) had his head on my thigh and a paw on Toby's paw. Losing Toby tore me to pieces... but seeing Skeeter and his loss made it even more heart tearing.
I also had an old cocker spaniel mix I'd rescued and given a forever home (with me). I had one tabby that adored him; cuddled with him every single night. When Onyx passed, Mickey suddenly took up with the border collie rescue and became fast friends with him. The two of them slept together, curled together, nearly every single night... especially in the winter when we had the fireplace going. When I lost Puter (the cat), the border collie looked like he'd lost a member of his herd... he knew she was gone, but he kept nosing around in the closets, etc., looking for her, I assumed. It wasn't too many months later that we lost Einstein (the collie). To this day, I think Einstein died of a broken heart... no matter how we tried to make things better for him.
If only humans could be half as "humane" as animals, this would be a much better world for everything living in it.
