Thank you all for the kind comments, they mean a lot!!!
We went to a local rescue shelter this afternoon to pet the kitties and one "found" us and we put a hold on her. In 2 weeks we will go back and if we feel the same we will bring her home! It is a lovely petite 2-3 yr old female pale calico that took to us and is very friendly!
To all, yes, Sonny was family, our son!! We can never replace him but we can develop a new relationship with a new pet! And yes, it does hurt a lot, both of us have been crying for the last couple of days!!
There will never be another Sonny, he was loved, spoiled, and will always be remembered!!
