You're "worrying about this now" because that's what responsible adults have to do- plan for what's important in their life. When renting or leasing a place- you can't blame a landlord for trying to protect against damages. So many renters are careless about damages &/or lie about having pets. When you have pets, plan for "security- damage- & cleaning deposits" being required, & hope they'll be open-minded enough to work with you.
