Tell them that you feel you can contribute alot, you're a dedicated, conscientious worker, and you feel you're the right person for the job.

A love for animals doesn't necessarily get the job done(in their eyes). You have to convince them that you would be the most qualified candidate for the position's requirements. In other words, they want a person that can accomplish given assignments, correctly, efficiently, and in a reasonable amount of time. Your love of animals will always help you with the job but it can't be your top priority.

Example: Someone wants a job at a bakery. Just because this person loves cake doesn't mean they will be the best worker the bakery can hire I hope this makes sense. You can tell how tired I am

Audrey: I don't mean to sound like you won't do a good job. I'm just explaining why this guy is saying this to you. Good luck. I know you'll do great!!
