I'm studying about themes for a theme system specially for animals adoptions.
I have doubts when use Categories, Tags or Post types:
Post-title : every post are titled after animal name.
Category: Animal type (dog, cat etc)
Status: for adoption/adopted
Post-body: text, pitures etc
Custom-taxonomies: size, color, etc
Don´t know if should use 2 categories for status like adoption and adopted. So within this it should also keep the same animal types (sub-categories) too. Read somewhere is not good to set 2 categories in posts (e.g: adopted and dogs), but I wonder why that is possible then?!
Post-types seems nice, but don´t know if has some use here.
Thanks for any help!
