I am in college studying veterinary medicine. I want to be a vet after I graduate.
Yes; it is a very important branch of medicine to treat the challenges of animals.  Do you have any particular specialty you want to enter?
I am thinking of dogs & cats, the most common household pets.
Do you think you might be interested in performing surgery or a nurse or a technician?  Each of these is an important part of the veterinary process.  
I think I would be a nurse taking care of the ill pets. I don't want to go to med school.
Yes, I can understand that!  Nurses play an equal role in the care of animals.  They help in the direction and fulfillment of the vets in making certain that food supplies and monitoring and treatments are observed.  You will play a large role in keeping pets healthy, happy, and living long!
That is the plan. Thanks for the encouragement. I can't wait to help the animals.
You may even be surprised at how many types of animals you will help.  Veterinary medicine is such a wide field the covers a large span of animals species, both wild and domestic!  Maybe a cougar will need help someday.  =)
