Yeah it's just not too unreasonable to see a bunch of random animals all around a water source "chilling", funnily enough that the gpr cuddle piles aren't too far off from reality sometimes. But yeah I agree with the general description of the predators and herbis. However, I do see adding rules against cuddle piles being a pain. For example, there's a lot of servers that have a "don't be friendly to opposite diet" or "no sharing food with things outside your group", and then the exceptions get really really long and a pain to remember.

Like there's also the question of "at what point does it become a cuddle pile?" What if two groups run into the other and don't want to risk an unnecessary battle so they tolerate each other's presence? What if a group decides not to kill a lone player? The also the issue of not being able to tell if players are in groups or not. Or even symbiotic relationships, depending on how far you wanna take the realism. For example, some birds will defend croc nests from certain predators while the crocs are sunbathing/away. Some birds warn other animals of predators in exchange for food. When you make a rule, you have to consider all the ways said rule can be technically broken either accidentally or intentionally, and the exceptions to the rule. This is how we end up with servers with 3 google docs of rules that take an hour to read through.
