I know exactly what you mean by a heart rat, but my conclusion is the exact opposite. When they die, yes you grieve at the loss of that special little persons unique love. But the fact that you got to experience that special love is the exact reason to fill your life with *more* love from unique, wonderful furry friends.
The only time you really lose that love is if you choose both to forget them, and to stop allowing new ratties into your heart.
I'm pushing somewhere around 40 rats that I've had at one time or another. I cry when any of them dies, but I know that the memories are forever and there is always more love as long as I choose to rescue the next one.
