I guess I'm strange because this doesn't freak me out? I actually think it's sorta neat... But I suppose I deal with grief differently than those who think this would lock them in a state of perpetual sorrow. I have photos of my dead animals everywhere in my house... I have collars, hair (I have a braid from my favorite deceased horse)... It's all happy memories. I LIKE being reminded of my animals, when they were alive and happy. Having, say, a cat sleeping on a pillow looking peaceful would just seem like a step up from a photograph of that cat napping.
Jeeze, I'm weird.
