Is it purely medicine or is a big part of that living conditions?
I guess it is a bit more nuanced than I formulated in my original comment. If your cat is healthy and dies of some kidney disease it is completely OK to heal that cat, in my opinion.
I just don't think a cat, as it stands now, is made to live to 30 years because of cell decay etc.
In my time I have seen people keep other beings in a miserable state just because they couldn't let go. They pump them full with medicine, not because they have a better life this way, but because they can't let go.
And those beings where completely helpless and suffering. That is just something I don't wish for a innocent being.
I had the same problem on my laptop not being able to get into the bios. Turns out the reason is that the f-keys (f-1 to f-12) where not registered as such on boot.
They are also the keys for volume and brightness etc. So when I pressed f-11 on boot it registered it as "Brightness up" and not "f-11".
The solution was to press "fn" + "f-11". Then it registered as the correct key.
You have the option to toggle the default on that. So that you press f-11 and it registers it as such and "brightness up" is "fn" + "f-11).
For me that toggle was "fn" + "esc". There also was a lock symbol on ESC so if ESC doesn't work search for the key which has a lock on it.
That toggle was also an option in the bios.
So yeah, wasted an embarrassing amount of time figuring that out.
Every month is month of wrath.
