Personally I am allergic but if office is thoroughly cleaned daily it shouldn't be an issue with visitors.
Recently I was consulting in Dallas where they had one, again, everyone knew it so we set up his own Instagram account!

This isn't multifamily, but I found a great post about getting the community involved with a "community pet".

We have a beautiful black female cat named Willows which is also the name of our community. She was once a feral but is now a peaceful, loving and very much an attention getting asset to our community. She sleeps all day in the office on a rug close to the entrance. Goes out at night.

She is an ice breaker and gives prospects a very positive feeling about our community. She no doubt is responsible for many leases. She helps make our community seem like a real home and not just a place to hang your hat.

Anything to add some fun!

We adopted an older cat, The Duke of Montecito, or Duke for short. I often referred to him as our fair housing kitty, as he loved everyone equally. He came when called to greet our residents and prospects. Residents came in just to see him and would sit for hours with him in their lap. People who claimed they did not like cats, made an exception for Duke. The issue came when I left the property, and the new manager was not a cat person. Duke now lives with me and has retired from property management.

Had a cool cat at a property that the client agreed on, I left the company, subsequently the manager left, within months the new manager and RPM opted to get rid of the cat. Fortunately the previous manager heard and asked to take him
