Regarding cat: she's doing fine, she's gonna get a thorough dental clean and some minor things done to her molars + extraction on July 6th, vet was happy she's doing fine despite the broken fang.
I took a look at the rail and noticed that the two last pins were soldered for some reason, luckly I still had the rail of my broken joycon so after I swapped them I was able to use it attached to the console
