I'm not even sure I'd call it a pattern :)
Writing variables to a template should be totally unneccessary if you're
just going to load it in that way, because of the way lazy-loading in
Ansible already works.
If you want dog to contain the value of cat, you can just predeclare dog:
dog: "{{ cat }}"
You don't have to write a variable file to load it.
