I'm very sorry for your loss of Mr.Nugget. He looks like he was a great friend and companion. I know how it feels, I just lost my Bobby and I buried him in my backyard last week.
There is nothing that can be said that will make things better. What we do is wait a period of time and visit the Shelter to see what is available. Over the years we have had great luck in finding kitties that can adopt us.
He looks like a sweetie. I'm sorry for you, I know it isn't easy.
So sorry to hear you lost him. It is never easy.
So sorry for your loss, looked like a happy companion!
