I completely understand what you mean...
When I originally offered to take care of my grandma's cat, at the time that I did, it was in the spirit of "in case of ANYTHING that might happen for her" having to go into assisted living or in case of her passing on.
So yes, it was to cover the bases.
And yes, it is good that even though I did end up taking the cat BEFORE my grandma passed on, so that I still also have my grandma in my life, my grandma sure does miss her cat all the time.
I'm glad that you love the cat, and that you wanted another cat.
And even though my grandma has four kids, none of them wanted poor Katie!!
They don't like cats, and only my grandma and I even like cats, and that's why I had to go 15 hours by car to get Katie, but that is what I promised.
Well, my grandma would have kept her cat to the very end, too.
She still asks my mom if she can come get Katie!
We cat-lovers are very stubborn like that!
Well anyway, I'm glad you have your Grandma's cat and that he is in a loving home.
I guess that's the way life goes. sigh.
