It's been quite a while since I wrote any kind of posts on Astarion's topic, as I thought I was more or so done with everything game, books and lore overall has to offer. Yet after randomly looking through some fanart I realized that people heavily associate Astarion with "rat" figure... and that doesn't really sit right in me.
Do consider this post not as a proper analysis but rather my flow of thoughts and not so processed feelings, shorter - maybe even a headcanon, if you please.
So, the core of my thoughts is that it isn't Astarion who is "the rat", speaking metaphorically, but Cazador. You don't have to go far to see the connection, as even his overly dramatic doors in Palace has an image of circle of rats on them, altogether with writings in his own native language.
That being said, we can also say that Cazador isn't just a "rat" but rather a "Rat King", so he's gathering all the rats "below him" to rule them. But there I think he doesn't just "gather" them - he, as it would be only fitting for his character, was degrading everyone down to being just a rat. No matter who you were before - now you are beneath him, now you are his "little rat".
So, there where I had funny feelings about the association of Astarion with rats. You see, I started thinking that "becoming Cazador's rat" isn't just about to become his vampire spawn, but equal to becoming loyal to Cazador, to seek his favor, to embrace the position he had given to his spawns. We can clearly see that in other spawns as Violet or Aurelia - they are happy to serve to their "Rat King".
Do we see the same in Astarion? Absolutely not. All the time he was fighting against Cazador and being his loyal spawn, maybe being the most disloyal among the whole group of seven. He rejects the very idea, trying his best to remain who he truly is, not Cazador's puppet.
I see Astarion more feeding on those "rats", also loving the comparison of him to cat from Neil's streams. Setting aside the real life where domesticated rats and cats can absolutely live in peace and still thinking in literature way, cats are bigger than rats, cats are more graceful, more dangerous, cats are predators and hunt those rats. And now apply this to the whole Astarion-Cazador situation. A rat tried to belittle a cat to a position below himself, yet we all know the end of this story.
The mouse smiled brightly; It outfoxed the cat! Then down came the claw, And that, Love, was that.
