Wow, I really enjoyed this story, @katleya. It is imaginative and richly told. You have populated it with interesting characters, and have built suspense, creating a very nice story arc.

I have a few suggestions for minor edits. They are very small, but I thought I would mention them, since your story is otherwise so nearly perfect!

In the first paragraph, the word inoculated is not correct because it indicates a vaccine to prevent disease. But the description indicates that it causes disease.

The cataclysms and the diseases inoculated to humans by cruel doctors

You could change "inoculated to" to "injected into". That would make sense.

In this phrase, the dialog reference is incomplete:

The next day Lilian does her ordinary work but stays behind to talk to Moni.
-What did they tell you? asks

The following sentence refers to Judith, a female, so "he" should be "she."

Instinctively, he began to sense things he did not understand...

And my last comment is that in the story, you mix up Judith and Lillian. The name of the person who stops taking the XKP substance changes from one to the other. So, if you go through your story one more time, you could fix those minor things and straighten out which of the women can talk to the animals and is pulled up in the spaceship.
