Yeah, that’s exactly right.
As for the second part, I’m not sure how to answer. Squeezing the partner is without a doubt adaptive, but squeezing anything that is roughly the same shape is a byproduct with no (strong) evolutionary pressure. Now, the question is whether functional necrophilia is adaptive or just a byproduct is very difficult to answer, but I lean towards byproduct.

Adaptive here means whether necrophilia occurs in order to still produce offspring, i.e. it’s ‘conscious’ (I use that term veeeery loosely here) or if it occurs just because the animals don’t recognize that the partner is dead.
I remember a paper about a frog species (not sure if it was the one from the meme) where the males participated in necrophilia, but they basically tried to squeeze eggs out of anything they grabbed. Living female, dead female, stone, sponge. All the same.

Damn, I’m getting flasbacks from that. I had to make a presentation whether functional necrophilia in animals is adaptive during my master studies. I had to read so many papers discussing the details. Conclusion: not enough evidence to conclude it’s adaptive.

Edit fun fact: in the 1920s there was an Antarctic expedition funded by the British Royal Society. The scientists described necrophilia in emperor penguins (I think), but the Society refused to publish the research to not sully the image of the animals. The paper was finally published some time after 2000.

Feline urine has a relatively small effect compared to feline saliva or fur.

I’ve failed to get that to work. How do you actually get additional languages?

I have used both used GitHub for sync and Syncthing. Both work pretty flawless, but I prefer Syncthing (or rather Syncthing-fork).

As far as I remember, synching to mobile is not easy with the GitHub solution (I only used it to sync between two desktops), but Syncthing works great on both mobile and desktop.
