You are very right about carnivores being among the main attraction in zoos. Once you take out the primates and the Elephant/Giraffe/Hippo/Rhino and maybe the Bison, that's where most of the focus tends to go.I mean, the context here is that large carnivora are in game, as in real life, extremely well represented in zoos because people like big carnivora and they are (often) relatively straight forward to look after in a zoo setting once you have the appropriately secure habitat down. But like along with elephants, giraffes and rhinos they are realistically always gonna be the star attractions.
And Planet Zoo is now running fairly low on larger species (excluding pinnipeds)
Sloth Bear
Spectacled Bear
American Black Bear
Brown Hyena
Sea Otter
Wolverine
Ethiopian Wolf
Jackals
Coyote
And honestly, I don't think we'll get all of those in the game, but the odds of at least 1 carnivora in any given full animal pack are gonna be extremely high.
I really like your list, though I'd probably remove the Brown Hyena and add in the Ocelot or Sand Cat, as the almost surely to come feline addition.
Going off the idea that we may only have 3 packs left, getting another canine and another feline seem likely. I'd like to think the same about bears but it has been two years since we got a bear. I really hope so though and that's its the Spectacled Bear.
