Because the Animal template is used on so many pages, it has a sandbox that you can use if you're not sure how the edit is going to turn out, or if you're not making a single simple update. The animal template also has a testcases page, so you can test changes to the sandbox before you move it to the main template. A few of the other widely used templates (like seed) also have the sandbox & testcases subpages.

I'm curious why you changed the data entry for the Size parameter. Was it having errors, or were you just trying to make the template smaller somehow?
