I know that getting another animal does not replace the animal that precedes it. It is silly to think such. Each animal is unique and has its own personality. But what it does do is bring our focus from depressed to engaged again. It continues the cycle of life, of our life together with our animals…cat, pug, cat, boston, cat, pug, cat, boston, and so on.
I feel it is important that there are 2 of each. Having not had one like myself growing up, I know how much it sucks. Even though Lucifer Sam is a little freaked out by Jasper right now, soon they will be couch snuggle buddies together…a little pack of two. Caligula was a hiss-monster with Apollo at first, but now they sleep in touching symmetrical shapes on the bed together. Plato grrrred at Lucifer Sam when we brought him home and snapped at his head. We had to keep them separated for several days until Plato acclimated to him. But after that, they were buddies until Plato died.
When I have my 2 sets of 2, I feel much more balanced, like life is normal. And I can remember all my other animals that have moved on fondly, but not have to cry myself sick about it.
