I'm sorry about Blacky. We have a black cat named Sophie. We've only had her for about 3 years. I agree though, 6 years is way too short for a cat. It's hard losing them. My brother has a cat named Jasmine and he's had her about 4 years. She came up missing about 3-4 months ago and still hasn't come back home. We don't know what happened to her. So, it's really hard losing something you love... Nothing anyone can say is gonna help the void you feel from losing Blacky. The only thing that will help some is time. I'm really sorry
