So I saw a user has created a post previously about unreading/uneating foods but it was dead since 2019.
Since the creation of the Bathhouse Cleaning Pools, it could be added (even if just a csc option?) to the pools to have foods or books removed from your pet. Some people adopt pets with a thought in mind for everything, including the foods/books for said pet, and find they already have things that don't fit the theme. If possible to do (and not make endless extra coding work) the cleansing could unlearn books and remove alchemy points (x amount of points per books unread maybe?) and uneat foods the user selects for each individual pet.

I like this idea, since I've made some mistakes reading or feeding to pets I did not want to... a way to fix that would be nice.
This would be a good feature. It could work like the sticker removal, where you enter the name of the item you want removing, to save having to search through pages and pages of items.
Exactly like what I was thinking actually. I am sure there is a way to make the intel loss work as well, like so many books removed is so many points lost or something like that. Idk. I just think it would be a really wonderful option.
I'm not asking to get the food or books back, that would be a bit much, but just a possible way to remove them would be great.

I like these ideas, and yep they do get Suggested.
There's no easy way to deal with AP loss and INT loss for books. I think it should be a mindwipe/brainwash machine that stocks in Bits & Bytes. It works kinda like the Gym Vending Machine, in that you are doing something at least a little bit unethical to your pet and you are using up Humming Power Crystals or something to power it up. It should also be somewhat un-precise and also erase a random number of other books read, because information is not stored as neatly in the brain as we think and this will compensate for there not being a good way to deal with INT and AP loss.
As for foods there could be a gaggmiwith spoon. Barfing foods out is never as neat as you think so also random other foods would be lost.
