What is the paw print with a circle around it on the bottom of my page?

Just noticed something different now. When I visit other friends shops, there is a paw print with the number 4 inside of it on the bottom of my screen in the middle. The number doesn't change when I visit friends shops that I have not visited today and earn paws. What is this?

That is your rating from liking neighbors shops. It can range from a 0-4. 4 as the highest.
