Interchanging the positions of 'About Us' and 'Meet Pets' in the navigation bar of Home page

**Describe the bug**:

In the current webpage layout, the 'About us' section is before the 'Meet Pets' section in the homepage(index.html) and thus it is logically expected that the 'About us' should be placed **_before_** the 'Meet Pets' in the **_navigation bar_** of the home page.
However this is not the case and thus it is hampering the user experience to a certain extent because of the non-sequential redirection within the home page.

**To Reproduce:**
Steps to reproduce the behavior:
1. Open the website
2. Click on 'Meet Pets'
3. Click on 'About Us'
4. See the non-sequential re-directioning of the webpage.

**Expected behavior:**
The re-direction should follow a systematic order as per the contents of the webpage when we are clicking the buttons of the navigation bar in a sequence.
