|Sorry to hear about the loss of your precious Coco.
There is no doubt that our wonderful pets can and do leave ADC's. Tiger and Rusty, two beautiful orange tabbies, passed 2 months apart last year.
Ever since they passed, there has been mysterious meowing and sounds they used to make, like bounding up and down the stairs. I have heard it, a friend of mine has heard it. It seems very real.
I feel hoping that you will be experiencing ADC's from Coco in the near future!
