@Ray Harrell , here is the wording of on my lease:
"Pets. Pets shall not be allowed without the prior written consent of Landlord and at Landlord’s absolute discretion. If permitted by Landlord, at the time of signing this lease, Tenant shall pay to Landlord a non-refundable deposit of $________ per pet. This amount is in addition to any other security deposit stated in this lease. Pet deposit will be held in trust by Landlord with security deposit for duration of lease. Any Tenant who wishes to keep a pet in the rented unit must sign a pet agreement addendum. If a Tenant allows more pets that are stated on the pet agreement addendum, Landlord may terminate the lease agreement with no return of any security. Tenant shall be responsible for the animal, its behavior, and any damage done by the animal. The Landlord shall have the right to withdraw consent and demand removal of any previously permitted animal upon the first complaint registered against such animal or upon evidence of injury or damage to person or property caused by the animal. Pet deposit is due prior to key pick up. Keys to the property will be withheld until all deposits are paid to Landlord."
