The intent behind this question is to determine if you appreciate animals in general, not just dogs and cats. Talk about some of your personal animal experiences, whether looking after your pet turtle when you were a child or finding an injured bird and nursing it back to health. If one particular incident or pet was responsible for your love of all animals, be sure to share that story and explain why it had such an impact on your life. Anyone can profess a love of animals, but the interviewer wants to see if you really mean it and share a connection with them.
