I'm so sorry for your loss of precious Koda. I live in AZ and was paranoid every time I took my little 5 lb girl outside; searching the sky for hawks and owls.
Don't necessarily give up the idea of another fur baby just because of the eventual loss. Didn't you have many wonderful, fun, comforting years with Koda?
I lost the fur-love of my life this week so I share your heartache. Coming home is the hardest...no barks, no kisses. The hope of a new little dog keeps me from spiraling down into the darkest depths.
Hang in there. It sounds like there are many if us that unfortunately feel your pain.
