No. They're very different, and not interchangeable.

Mail order or shop?

NO. I realize there are some people who think cats can be vegan, but I
find it morally reprehensible that such people arrogantly force their
alternative lifestyle values on a helpless creature nature has seen fit
to live by its own specific set of values. Cats do not eat rice and
beans. They eat fish, mice, meat, and offal. Please don't go so loopy
into veganism that you project your peculiar sensitivities onto other
helpless species.
