They are amazing creatures. Time for me to tell a story that you won't believe:
My mom had a Russian blue cat by the name of Mist. He survived getting hit by a car when he was two and survived cancer when he was seventeen. I knew him all my childhood. He was probably the nicest cat you'll ever see. He tolerated me as a little kid, which most cats probably wouldn't have done. He was an excellent hunter; my parents had no problems with mice when Mist was around.
When he was twenty-one (and I was ten at the time) it was his time to go. We were moving to a new house, and he had to be put to sleep because his cancer was coming back. My mom had a tough time with it. We buried his ashes somewhere, I don't know where exactly, but this next part is the one you won't believe.
My mom heard a cat mewing, and she was spooked. She woke up my dad saying that there's a cat in the basement, and that she wanted him to check it out with her. She woke me up with her scream. And I'm wondering what's going on, so I head downstairs, and saw a painfully-thin cat who looked exactly like Mist. Russian blue, down to the eye color. This cat was mewing for food, it had probably been starving from the journey, and we had no idea how any cat could've gotten into our basement. So, we went to get food, and I tell my brother in the morning that we had a cat.
We sent up flyers for a lost cat, all the way up to three-hundred miles away from us, and nobody answered. So we went into the vet to check on the cat...and we find out that she was a girl. And pregnant.
We named her Misty in honor of my mom's cat. She gives birth to two kittens: Valkyrie (a Russian blue like her mom) and Phoenix (a huge Maine Coon with the same green eyes as his mom). We gave Valkyrie away, which is something that I wish we hadn't done. We kept Phoenix, and...well, that's the story.
