I haven't had too many problems. Usually after talking about stuff like my job, my dog, etc, I'll disclose that I also keep exotic snakes. I show them a picture of my current setup so that they can see I keep them very clean, organized, and professional looking. I explain that I keep them as a hobby and am interested in biological research as well as breed them which produces additional income. Most landlords can see that I am very responsible with them and take them very serious past just having a bunch of pets. A lot of times they are very curious about them and ask lots of questions.
