Animal care should not be stagnant. It should always be evolving and improving.
This applies to breeders, hobbyists, “casual” owners, everyone. It also applies to anyone who keeps animals for profit. If animals are raised to be eaten, they should still have the most up-to date care available.
If you find something that works, great! Use it, recommend it, whatever. But keep doing research. Keep learning and trying to improve. There are very few things that were done 50 years ago, even 20 years ago that have not changed or been improved upon since then.
If a breeder, store, rescue, etc. tells you that they’ve been doing something a certain way for more than a decade, start questioning.
look, I’m not against veganism, I don’t give a shit what you eat, I just think we should focus our energy on changing how nations and corporations act, rather than policing individual people’s diets. Individual people’s diets will change when they’re structurally able to change them.
