Talothral likes weird-lookin' ladies (but who all weirdly-enough have genitalia that are completly identical to human women, of course), but they're not animals. He always has, all the way back to the troll side girl from Sorcerer and, uh, almost all the women in Terminus Reach Sentinel.
If you're referring to the panther, she is not a romantic or sexual interest. She's the MC's familiar (basically an intelligent animal bound to his soul who can help him with magic and protect him). There is no bestiality in any of Talothral's games.
