If one was able to alter a non-porcine treif animal to make it chew its cud and have split hooves, would that animal be kosher?

This question If a pig was genetically modified to chew its cud, would it be kosher? already discusses pigs and the answers mention that a pig would still be treif, though they don’t agree if other animals would be included in this halacha or not (see @Shalom’s answer which seems to imply that all animals would still be treif vs. @menachem and @ephraim’s answers which seem to imply that the Halacha is only by pigs) Based on that, would there be a difference in other cases, for example:

Would there be a different Halacha by birds or fish? Why?

Would there be a difference for what was specifically written in the Torah as treif (like pigs) and what wasn’t (like lions)?

Would there be a difference between beheimos and chayos?

  • Your question also still talks about pigs so it's still a duplicate. You could maybe edit pigs out somehow using the knowledge you gained at that post. Or maybe edit to generalize that post. Or both. Or something else. See too judaism.meta.stackexchange.com/q/4795/759 – Double AA Jun 4 '19 at 14:05

  • I still don't feel that is wise. There is so much duplication of labor happening still. I think there's a better solution. – Double AA Jun 4 '19 at 15:20

    If you're in a rush because you have such a genetically modified cat shechted and salted and cooked in front of you, please consult your rabbi. Otherwise there is no rush for me to need to step in. – Double AA Jun 4 '19 at 15:24
