Why aren’t animals infected with cordyceps?

I’ve always praised The Last of Us for how realistic it is. A fungus that infects ants and takes control of their body mutating to withstand human body temperatures because of global warming isn’t completely far fetched. I’m not saying it will happen, but it’s definitely more realistic than most other zombie viruses with little to no explanation (The Walking Dead as an example)

What doesn’t make sense, is how there’s no infected animals. Cordyceps started in animals, and withstanding higher temperatures should make it perfectly capable of infecting larger animals other than humans.

Did the fungus just pick-and-choose which animals to infect, or is there another explanation for why animals aren’t infected in The Last of Us?
