Oh, Portia
Your post made me cry too. I am so sorry, and no, you are not a bit crazy.
I lost a little one I was attached to at six weeks a few weeks ago and cried like a baby for two days, she also shadowed me, if I had her for two years I would still be crying about it. It doesnt take long to get very attached, and Crazylegs made herself your pet and your friend. We get special ones like that now and then.
I consoled myself to think my brother, who dearly loved all animals would be delighted with taking care of a new one over the rainbow bridge.
My condolences to you and may her spirit have lots of goodies and treats on the other side, yet still watch over you when you need.
Jill
