Hi,
Great questions. Yes I had experience with animals, but it wasn't extensive. I worked in a kennels and cattery, but I did emphasise my passion for animals and their welfare and demonstrated it with evidence, i.e raising money for a donkey charity and spending years researching into cruelty free products and only using those products. You will definitely need some experience and being able to demonstrate why you are passionate about your chosen course, but it doesn't need to be research or anything like that because you are doing an undergrad degree. Please let me know if i can help you with anything else.
