Poor kitty! Glad you found her, people are unbelievable! If you think she may have an injury to her foot, I would strongly recommend bringing her into the emergency vet to be examined. They will be able to tell you whether or not the affected area is savable or if it is something that should just be left to resolve on its own. I'm sure this is not what you had intended on doing with your holiday weekend, but Mia thanks you for your love and care! Hope this helps.
