That is a tough thing to go through, I know that our pets/companions have feelings and emotions and are family. When I had to put ole Spanky down, I cried like a three year old. But I try to remember that the last thing she remembered was my warm touch, kind voice and loving touch. Don’t know if our animals go to heaven, I like to think that they do cause God knows how we felt about certain animals then he will surely give us that reunion again.
