I cant really offer anything much of criticism as of yet. The story starts out with the MC getting a weak pet cat as a contract beast who needs to be able to fight with ferocious monsters. He gains a nurturing system that allows him to progress the contract beast's state as long as the MC does things that make it happy. He can upgrade the quality of the bloodline as well as it's level progression. He is also able to increase other aspects of his beast.To start off his little cat is female, so based on the title I was actually expecting it to quickly gain human form. From what I have read so far it requires some nurturing. Also even before gaining human form the cat has some human attributes, such as jealousy and affection. The cat always wants to sleep in his bed with him. This should not be a problem, but it looks like in CH20 it gains a loli-human form. This could pose a problem with many of the readers here. I will update my review based on further reading.As of now I enjoyed the content and found it to not be displeasing from the storytelling standpoint. It seems to be better written then many similar stories, though the system design and progression seems to be a bit weak.
