I am so sorry you had to have your beloved cat put to sleep. I've gone through that and it is the worst grief I have ever felt in my life. I was sobbing like a baby in front of a total stranger (vet assistant) when I held my Nellie for the last time.
They are so intuitive, aren't they? They know when we're hurting and they'll come up and stick close to us. He WILL always be with you. I don't know if you believe in Rainbow Bridge, but I certainly hope that in the next life I will be reunited at that bridge with all the wonderful pets I've lost.
