You might want to try soft claws. They’re little plastic caps in the shape of a cat’s nail (except soft not pointed) that you fill with a non-toxic adhesive that comes with the pack and attach to the cat’s nails. Over time the cat naturally sheds their nails and the nail caps come off with them and you just replace them again when that happens. They say it doesn’t bother the cats and they don’t even notice but I think they’re exaggerating a bit there because my cats hate the process of having the nail put on which makes me feel bad but once it is actually on they quickly forget about it and it doesn’t bug them.
It’s not a perfect solution the claws are finicky to work with, the applicator for the adhesive gets clogged with dry glue, the cats don’t really like having the nails applied, the caps themselves are really quite expensive and some items like wooden furniture, still get damaged even with the soft claws but the damage in such cases is still greatly reduced and for soft items like a couch it pretty much stops them doing any damage.
One thing to keep in mind though, don’t buy cheap ones off eBay, they’re not worth a cent, the cats hate them for some reason, they don’t seem as well manufactured and they don’t come with little cleats inside to help lock it in place. Because the cats absolutely hate them so much and are definitely bothered by them they immediately pull them off straight after you’ve applied them and they’re just a waste of your time and an unnecessary source of stress for your poor kitty. I’ve found 2 brands that seem to actually be good and they’re both a lot more expensive then I’d like but at least you can buy a supply of several months and save your possessions from destruction. The two that worked for me are Soft Claws and Soft Paws. Claws seems slightly cheaper. I think they might actually be the same product since they have the exact same artwork and typeface for their packaging and logos and the caps themselves seem to be identical, one of them just says claws and the other paws. Weirdly enough they’ve both chosen to use Garfield on their packaging and somehow I’m fairly sure neither has paid for the privilege.
I can’t foresee Lemmy specifically reaching levels of popularity comparable to platforms like Twitter or Reddit. Barring some very strange disastrous upheaval of the whole landscape they and their ilk will continue to be Leviathans even with decisions at the top that look like outright sabotage. There is so much inertia. Maybe those two examples might disappear, but only if they’re devoured by another just like them.
I can see Lemmy and similar Federated platforms with their quite sizeable yet comparatively miniscule user bases carrying on as they are and even growing a little bit and having some effect on the zeitgeist with the occasional piece of local culture seeping in to the wider platforms though people there will likely not know that’s where it came from. I also think efforts like Threads or likely something similar that comes after will be where the fediverse meets any mainstream success essentially becoming part of those bigger platforms in some way I can’t yet predict in detail.
The big appeal of Lemmy is ideological and technical, this will always limit the number of people drawn to it. If there weren’t already giants in this space that wouldn’t matter because there’d be a snowball effect that would draw crowds who came because of other people not because of any interest in how the platform functions or ideals to pursue and with those crowds could come more crowds until you have a critical mass. But with the situation as it is now, the big crowds that draw yet more crowds still, are elsewhere so you’ll only ever have enthusiasts or ideologues that go out of their way to be here.
