For me it is the simple pleasures they react to that give me a laugh and a warm feeling. I really enjoy all the apes,dogs cats and the large animals taking care of their young. It is always peaceful althought I detest most zoo's. I appreciate those that take the wounded or sick and help them recover and then return them to nature if possible. I plan to have my ashes mixed with my favorite dogs ashes and spread in nature when the time comes.
