I wish I could say something to reassure you but I can only admire her for having such caring humans to look after her.

Cat didn’t seem to mind camouflaging into the kids chalk artwork. She did mind though me having to clean her afterwards.

It relates to stuk, which means broken in this context. It can also mean a piece. You could read it as (broken) into pieces.

German, as well as other germanic languages aside from English actually use verb second structure. True, that the main part sits at the end if there is an auxiliary verb. Example word for word translation would be: Tomorrow go I to school. Or Yesterday have I cake eaten. https://en.m.wikipedia.org/wiki/V2_word_order

What other posters said, respond with the blinking. My son calls them eye kisses. It shows trust. In case you’re unfamiliar: you look at her and slowly close your eyes for a second. She might mirror it. Facing a fierce predator such as the one you pictured and confronting it willingly blinded, even for a second, takes courage. She’ll honour it most likely. Also food and clean water, preferably placed in separate locations.

Hard to say, but if the 5V natively to the machine is shot, I’d expect the unit to not work as its systems would depend on it. I assume you measured 5V in reference to the machines GND. Double check your meter against a known good 5V supply (your adapter).

If they both are power supplied, and have ground connected then what would you need the 5V connection for? Some devices that externally supply power can come with a protection diode to prevent looping power back to prevent the scenario you described but looks like that’s not needed. You would have to know the protocol used such as baudrate, bitlength, stopbits and parity. If you don’t have that info try common baudrates (115200), 8 bits, 1 stop, no parity.
