I thought I should post this here since I'd touched on the topic in my last post.
Tiger is gone.
I took him to the vet on Saturday and just after 3 PM, Tiger was put to sleep. He'd been suffering from intestinal cancer and there'd been some growths starting to appear on his skin as well.
He was a little over a month shy of turning 10 years old. For a cat, he was still fairly young (only about 50 in human years) and it hurt very much to see him go so soon.
It was very, very rough, but I am glad he's no longer suffering.
I hope he is chasing and playing with the squirrels now.
