As a visitor
When I have added pets to my favorites list
And I visit my favorites page ("/favorites")
Next to each pet, I see a button or link to remove that pet from my favorites
When I click on that button or link to remove a favorite
A delete request is sent to "/favorites/:pet_id"
And I'm redirected back to the favorites page where I no longer see that pet listed
And I also see that the favorites indicator has decremented by 1
