## Description
<section id='description'>
The code for an ordered list (`ol`) is similar to an unordered list, but list items in an ordered list are numbered when displayed.
After the final second section' last `h3` element, add an ordered list with these three list items: `flea treatment`, `thunder` and `other cats`.
</section>
## Tests
<section id='tests'>
```yml
tests:
- text: 'Your `ol` element should have an opening tag. Opening tags have this syntax: `<elementName>`.'
testString: assert( document.querySelector('ol') );
- text: Your `ol` element should have a closing tag. Closing tags have a `/` just after the `<` character.
testString: assert( code.match(/<\/ol>/) );
- text: The `ol` element should be above the second `section` element's closing tag. You have them in the wrong order.
testString: assert( $('main > section')[1].lastElementChild.nodeName === 'OL' );
- text: The three `li` elements should be nested inside the `ol` element.
testString: assert( [ ...document.querySelectorAll('li') ].filter(item => item.parentNode.nodeName === 'OL').length === 3);
- text: You should have three `li` elements with the text `flea treatment`, `thunder` and `other cats` in any order.
testString: assert.deepStrictEqual( [ ...document.querySelectorAll('li') ].filter(item => item.parentNode.nodeName === 'OL').map(item => item.innerText.toLowerCase()).sort((a, b) => a.localeCompare(b)), ["flea treatment", "other cats", "thunder"] );
