Can you do work experience at the RSPCA?

Yes you can do work experience at the RSPCA, just contact them at the time of your work experience as places are taken quite quickly because many others like yourself are interested. Only consider this if you don't mind getting down and dirty, by that meaning having to clean cages/kennels mainly after dogs and cats... if you are considering a career in animal it would be a fantastic oppertunity for you and would help you to gain a placement later in your life when searching for volunteering jobs, etc.
