You will so be a dog person once you have your pup home. I can't believe how much love I have for my little girl. I would take her everywhere with me if I could.
I too was a cat person. My cat was almost 18 when I got my pup. I knew kitty would be going to the Rainbow Bridge. She did live to be 20 even with diabetes. Tabitha and Calleigh would tolerate each other. When Tabitha passed last March Calleigh looked everywhere for her. My friend is a "Cat Vet" and she came to my house and put her to sleep. I so appreciated that. I let Calleigh sniff her. I think that did help. I have a little area that I keep with Tabitha's picture and collar. When I dust there, the bell on the collar will ring sometimes. Calleigh starts looking for the kitty. It's a little sad, but nice that she remembers her too. You will have the time of your life with your new pup.
