I'm really sorry to hear that Viski is suffering and nearing the end of his time with you but being aware that this is the case provides you with the opportunity to enjoy that time as much as possible. I've experienced the loss of a 'best friend' myself and know it's a difficult thing. He's a beautiful looking wee guy. :)
The imagery did a fine job of disguising your words and true direction of them. The post was really, really clever mate and worked well, I'd say. :)
