Last year, my six month old kitty, Mick, crawled under the sofa when I lifted it to vacuum under it, and I didn't see him. I killed him when I put the sofa down, and he was there for forty five minutes before I realised. I tried everything, mouth to mouth, cpr, everything, I couldn't save him. A year on, I'm still having nightmares. I sat on that sofa whilst he was under it. I can't get past it.
I've never killed anything before, and it's eating me up inside.
What do I do ?
