Seeing as the archetypal livestock species in the GrimDark is Grox and I don't see that many Grox around today's farms, it's safe to infer that they are tolerant of useful Xenos species, at least as long as they can be subjugated in some fashion. (With Grox, lobotomisation).
Obviously, a hardline puritan would probably draw a different line on the matter to more moderate Inquisitors, but let's be honest - between dealing with an actual threat like Orks or going out and shooting a load of cat analogues, I think even the most puritanical Inquisitor has some sense of priorities. (Even if the latter would be a lot easier).
I'd say go for it. You might however find staunch puritans need less of an excuse to shoot the thing.
