I recently had to put my cat, Blackjack, to sleep. 
Thats unfortunate. It is a difficult decision to make. Sometimes we are put in those situations and they take a toll on us.
He was 15 and his kidneys were failing. It was really hard for me and my kids.
I hope he is in a better place now. How did you have Blackjack for?
Since he was 4 months old. It was so hard, but the right thing to do.
So you all had relatively all his life. Yes, it was the right thing to do. Did you get another pet instead?
