ESA letter from new mid-term tenant

[Matthew Purvis]

Hello BP,

A new Tenant just moved in on the 16th for a mid-term rental. She gave me an approval letter from a RN saying she requires an emotional support animal for her mental condition. It specifies a Cat. On her application she stated no animals. The letter looks like a template off the internet. The address of the RN’s office is a Fed Ex office. Also this is an AirBnB property for us in the summer time and my family does use the unit for summer getaways. My Wife is highly allergic to cats. This looks like a duck and sounds like a duck. Is this a duck and any suggestions to counter her letter?
