They were depressed looking. My dog was listless and wouldn't play with his ball or catch his stick. His eyes were so sad. He would lie on the spot where I buried her. I eventually got another companion for him and he did a complete turn around.
My cat wouldn't eat for 3 days, and she would restlessly walk around the house giving out a soul wrenching miaow. Intense hunger I think drove her to the food bowl. I never replaced my Dutchess simply because I couldn't bear going through that again.

I understand that and no I have no plans to get another.
