Did you not read "no bedroom action"? Because bestiality is only if you have a sexual relation with an animal. And since this obviously wouldn't happen in an E rated game, there's no need to worry about bestiality.
Even on the chance you could, it wouldn't be bestiality, it would be xenophilia. Bestiality requires that the creature of a different species either does not meet or exceed the brain capacity of a human, or cannot communicate consent. Since these creatures are of a different species but are both as intelligent as humans and able to give consent, it's technically nothing illegal. Though that's probably only because world governments haven't really come upon an issue like this, since we don't have anthropomorphic cats walking around. Not yet anyways.
...well, that went a little more in depth than I thought. But point is, simply dating a villager isn't bestiality.
