Polish pet selection feature & unit testing

[Elielh17]

Polished the Pet Selection Feature by adding new animations, and integration with actual pet data. Developed a unit test for the pet selection feature to ensure it functions correctly across different scenarios and integrates seamlessly with local storage once implemented. And finally some code refactoring/cleaning.
