Sure. At 14 I did 2 weeks work experience with a vets, and after the 2 weeks, everything worked out so well and I ended up staying on with them paid, 3 days a week until the age of 16. I did everything that I could do without a licence, including helping out with the animals and front of house. As soon as I hit 16 I got a job at Pets at Home for a year which had more responsibilities.
I also worked at a zoo for 6 months, and also did voluntary work experience for 1 month at Tesco, 1 month at an Aquarium, 3 months at John Lewis.
So I thought for an 18 year old I did my fair share of experience and since I have been applying for jobs with both animals and retail, the only jobs I can seem to find yet that will even ask me for an interview are cold callers -_-
