Now you have fur everywhere and a guest that is allergic to pet har checking in  2 hrs from now.

I don't allow cats (at least so far, I'm allergic).

I used to rent to dog owners, but not cat owners, I'm allergic to cat hair so it was an absolute with me.

The ones I can think of are: allergies (other tenants might be allergic)noise (my bird is the noisy one in our household)property damage (yes, the little dog who is from California, pees in the house sometimes..ugh)Fear (my big dog is 110 pound black lab) of Dogs/Cats/AnimalsFear of lawsuits if the animal hurts someone elseI'd like to discuss what can be done to alleviate these and any other objections as much as possible.  

Good guy:  If I thought her deposit might cover the damages, I'd tell her that you love dogs but some people are allergic and so she must go and If she'll "clean up really good" and can be out in 7 days (or whatever time you choose) you'll give her X dollars. 

I would say I have a tenant who is seriously allergic and for his medical condition you simply can’t have animals in the building due to his condition

We miss how they used to race around and chase each other, and especially enjoyed the binkies (a special bunny happy dance.)As for the allergies, I suspect, that if you are allergic to cats, you may be allergic to bunnies.

Unfortunately, the company I work for has a Title Company connected to it, and is "allergic" to investing-issues/circumstances.

People with serious allergies don't build a new house without consideration of what they are allergic to (i have a family member with this issue). 

I am allergic to cats so have an obvious bias and don’t allow them period their smell can do far more damage than a typical dog will do.
