starting new job as an animal care technician

I've worked with animals for the past 6 years but never in a laboratory setting. I have experience working in dog grooming as well as pet store experience working with small mammals, birds, reptiles and amphibians, and fish. I would be taking care of small rodents, such as rats and mice, but there's another facility with leopard geckos, sheep and other animals that I may be interested in depending on how it goes at this facility.

Does anyone have any recommendations as to what to wear? And any advice or information would be appreciated. I'd also like to hear about people's experiences as well. Thank you!
