A Bengal Tiger has been removed from a carnival owner due to neglect and mistreatment. A local petting zoo agrees to temporarily accommodate the tiger - affectionately named Benny - until the SPCA can clear out and repair their only appropriate shelter. Veterinary student, Peter, promptly volunteers to care for Benny, providing food, water, and some limited, and badly-needed medical and dental care. From what we have learned about torts this week, please discuss factors that should be considered by the petting zoo before accepting Peter's offer?
