Insane dream idea: would it be possible?

[xAnthemia]

I have just woken up from an insane lucid dream where I have spoken to my ball python, Noodle. Quite an interesting conversation, but that's not the point of this post. During the dream, I had an idea, and I'd thought I'd ask the ball python experts on this site as to whether they think such a thing would be possible.

So, at the moment, ball python food consists of mice, rats, gerbils, etc. A problem with this food that some people have is that if the snake does not eat, another life has been taken for no reason (providing you do not refreeze, which I do not). Another issue is that it can be a pain the arse depending on your situation (you can blow it up by heating it a bit too much, etc). It's fine for how it is, but I wondered if it could be made better...

What happens if we just had a block? A very small block, or maybe something in the shape of a mouse. How many of you think it would be possible that, if we had scientists on board, we could create some kind of food item that can be grown in a lab, filled with all the nutrients, vitamins, etc. that would come in your typical rat. You could have different amounts of nutrients etc. to represent different stages of rat (pup, jumbo, etc.). Of course, in this hypothetical, it is all ethical and the snakes enjoy it (or at least show no signs of discomfort). How many of you think this is theoritically possible and realistic?

Now, this is just a random idea with its own heap of ethical issues e.g. How do you test it without harming any snakes? However, this is not what this post concerns. This post merely seeks to ask how many of you think this idea is insane and would not work, and how many of you think it could, one day, be possible.

(This is what happens when you lucid dream).
