Smaller Animal Hitboxes (1.10)

With this mod all adult animals (base game + dlc) will use the respective offspring hitbox. Exceptions are the Grey Seal and Penguins, those now use the baby Giant Otter hitboox since their own juvie hitboxes prevent them from detecting deep water, so make sure to double check their habitats to see if they're still escape proof. This means they can use all the smaller doors where normally only the baby animals would fit through and reach smaller spaces in the habitat as well.

Obviously this can lead to some clipping (as you can see in the pics) when the doors aren't high enough etc. so if that bothers you don't use this mod.
