I am not a cat person but I do appreciate how a pet becomes a part of your family and how significant the loss can be. I had to have the vet put my pal Elmo to sleep just before Christmas last year. After being part of my life for about 13 years Elmo left a big gap in my life. Even though we had already acquired another dog earlier in the year it wasn’t the same without Elmo around. For months afterwards I’d glance over at one of his favorite spots and seeing it empty was a shock all over again. Its a good thing dogs don’t understand English or Rudy, the Chocolate Lab we bought in the spring of 2008, would surely have developed some sort of complex. Everything he did got compared to how Elmo would have done it, usually in the context of how much better Elmo was.
Sorry for your loss.
