I understand why vegans would be unhappy with that answer but it is the way it is.
I don’t. Veganism is about the fact that humans can live without animal products, which is true. Not accepting that actual carnivores exist, even being unhappy with this means you’re well in extremist nutjob territory.
There are plenty of vegan friendly pets to choose from too. Rabbits, guinea pigs, hamsters, chinchillas, pygmy goats ect. If they are willing to accept insectivorous animals that list gets longer.
Why choose a pet like a cat if their diet is a philosophical problem for them? Choose a different animal.
I’m aware of some vegans stances being against having pets, but if people are feeding their cats and dogs a vegan diet at least some portion of vegans aren’t against it.
For folks who want pets who are also vegan they should choose a species compatible with that instead of forcing it on an animal who’s biology isn’t going to thrive under those conditions.
