Barbara, I'm so sorry I didn't see this thread until now.
I was out of town when you first posted this thread and I haven't had time to catch up on Pet Talk until now.

I'm so sorry to hear that your handsome boy Tigris has gone to the Rainbow Bridge.
He was one of my favorite PT kitties.
I know how hard it is to say goodbye to a beloved kitty after so many wonderful years together.
I'm sure Samantha will see him up at the Rainbow Bridge.
Sending hugs to you, & Siegmar & Filou too.
