Totally agree that the game currently lacks any cats that behave/move in ways more reminiscent of true small cats. But I also don’t see Frontier putting in the extra time to get all the movements more accurate, whether it be through the already in-game Eurasian Lynx or a future small cat in DLC. They’d likely just “speed up” the same animations already used on the current Eurasian Lynx/Jaguar to make them feel more adjusted to a small creature. We already saw this happen with the Fennec Fox, as it use the same animations as PZ’s large canids.
Additionally if Frontier were ever to introduced new felid animations/behaviors, it’d be only through a new, paid-for DLC species. Never has a species in PZ received any major overalls after they were made available to the public. So I don’t find the odds of Frontier revisiting the Lynx high at all unfortunately.
