In my view as a long-time moderator, the purpose of moderation is conflict resolution and ensuring the sitewide rules are followed. As reported today by !vegan@lemmyworld, moderator Rooki's vision appears to be that their personal disagreement with someone else's position takes priority over the rules and is enough to remove comments in a community they don't moderate, remove its moderators for the comments, and effectively resort to hostile takeover by posting their own comment with an opposing view (archived here) and elevating it for visiblity.
The removed comments relate to vegan cat food. As seen in the modlog, Rooki removed a number of pretty balanced comments explaining that while there are problematic ways to feed cats vegan, if done properly, cats can live on vegan cat food. Though it is a controversial position even among vegans, there is scientific research supporting it, like this review from 2023 or the papers co-authored by professor Andrew Knight. These short videos could also work as a TL;DR of his knowledge on the matter. As noted on Wikipedia, some of the biggest animal advocacy organizations support the notion of vegan cat food, while others do not. Vegan pet food brands, including Ami, Evolution Diet, and Benevo have existed for years and are available throughout the world, clearly not prohibited by law in countries with laws against animal abuse.
To summarize, even if you don't agree with the position of vegan cat food being feasible, at the very least you have to acknowledge that the matter is not clear-cut. Moreover, there is no rule of lemmy.world that prohibits those types of conversations unless making a huge stretch to claim that it falls under violent content "promoting animal abuse" in the context of "excessive gore" and "dismemberment".
For the sake of the argument, even if we assume that the truth is fully on Rooki's side and discussions of vegan cat food is "being a troll and promoting killing pets", the sitewide rules would have to be updated to reflect this view, and create a dangerous precedent, enabling banning for making positive comments about junk food (killing yourself), being parents who smoke (killing your kids), being religious "because it's not scientific" and so on. Even reddit wouldn't go that far, and there are plenty of conversations on vegan cat food on reddit.
Given Rooki's behavior and that it has already resulted in forcing the vegan community out of lemmy.world and with more likely to follow, I believe the only right course of action is to remove them as a moderator to help restore the community's trust in the platform and reduce the likelihood of similar events in the future.
I wonder if we feed our animals with "vegan food" for a year, would they start to choose that instead of meat or meat based food?
Man, I've had cats off and on my whole life.
You can offer kittens freshly weaned anything you want, and they'll go after the stuff that smells right.
You can feed a cat any brand of food, and if they catch a bug or a rodent, or a bird, they may well eat it, or leave it on your pillow as a gift. Kinda rolling the dice which one tbh.
Cats are predators driven by instincts. A kitten rescued after being separated from its mother, raised by hand and then runs across something that sets off the prey drive will try to catch it. Adult cats that aren't even hungry will engage in hunting behaviors because it just flips the right switches in their brain.
Animals? They have almost zero choice in their food. When they do have a choice, they'll eat what smells right, and/or acts like food. You can't train koalas to eat meat as their main diet, and you can't train cats to not eat meat. At best, as an animal guardian, you provide them with limited choices, and they eat or starve (if the food isn't close enough to being food for their instincts, they won't even try to eat it).
Frankly, anyone taking a predator as a pet and not being willing to fulfill its basic needs is dumb. They're choosing their wishes over the care of the animal, just to fulfill whatever belief it is they're following.
You don't want the animals in your care to not eat meat, don't get animals that eat meat at all. No dogs, no cats, no snakes, nothing like that. Go adopt a bird that people didn't know how to take care of and dumped at some rescue. Pick the animal companions that fit your life choices, don't try and shoehorn yours into their existence.
In other words, vegans keeping meat eating pets are hypocrites because they're exploiting animals for their own preferences and needs instead of the animals'
