I would make the copies and all, but before you go pushing buttons make sure you are in 100% compliance with the lease. Some leases state no pets and even if your landlord verbally said it was OK to keep a herp they can use the contract and then you have a heck of a time proving the verbal agreement. Also lease information normally has some limit on pets and normally it is 1 or 2, this is designed to keep people from having 20 cats in a 1 bed room apartment and stinking the place up. Mammals need more room than herps, but most leases do not differentiate. If your Herps have you in violation of the contract or a state code they have you by the scruff of your neck and can pretty much do whatever they want to, signed lease or not. That is incase you can't create a situation that puts you in compliance.
