The Loss of a Pet - Ruminations

I am awakened with "Koko died, Koko died, Koko died." My husband is saying this to me with tears in his eyes. Our beloved and handsome 10 year old Maine Coon, Kokopelli, has died... way too young. Kokopelli, Koko Pop, Koko Lo-mo-po, Popster, Big Dude and Koko Smelly (when he was a baby he often had diarrhea). I'm assuming he died of cardiomyopathy, a genetic heart defect that is often found in Maine Coons. As a woman of a certain age, I've lost many pets in my life time. I can still name most of them... Corkie, our first dog, then we had a series of Siamese cats, then along came a chihuahua named Putsem, a derivation of Czech words which means come here. Then I had Fat Cat, Weenie, Scaredy Cat, Frisky and Maggie, and of course, Koko. I still have Bocce, a Main Coon and Koko's brother and Bella Blue, a Siamese mix. Even into my twilight years, I will have pets but I will have a plan in place for them. I certainly don't want them ending up in a shelter. So, here are just some thoughts:
The cycle of life... As you can see, I have a long history of having pets. So, one would think that after a while one would become a little "tougher" in handling the death of a pet. But, for me, it has gotten harder. Maybe it's because I no longer have all of the other stuff that one goes through in life taking up space in my emotions.
