Tenant asking why I am not renewing lease

Hello BP, I just sent a non renewal letter to my tenants and they have received it and are asking why I am not renewing their lease. I know us as landlords don’t have to give a reason but I just want to hear from y’all to see how y’all reply to the tenants. By the way, I am not renewing because they have broken the lease on several occasions such as having pets, too many “guests” in the home, and also they don’t keep the house cleaned. I want to avoid telling them this because I feel like if I do then they’re gonna get mad and return the property damaged and dirty.
