I saw a pet shop hiring today. Do you know if I can apply?

You can try. People say that you can have experience or not. Is this not suitable for your situation? I won't know until I go. No, it's nothing! Just make friends. Anyway, there is no professional knowledge, experience and technology to test you. What are you afraid of? Opportunities are really hard to get. I am in the same situation as you. I like small animals, but I have no professional experience. Ask pet shops and hospitals, they must be veterinarians or have studied pet grooming.
