Yes we would not have adopted Thor if he wasn't already old and worn out. His days of being wild are long gone. Hell you could leave the front door open and have a cat walk by and he is like, "Yea whatever, its hot out there. Have fun, I'm going back to the couch".
We are hoping we can just give him as many years as he has left in as much comfort as possible since the previous owners were dickcheeses.
