Not a good idea having cat in a condo, cats dont <deleted> on their own doorstep, especially if the project says "NO PETS"
A friend of ours has a identical apartment to us, and she decided to rent it our long term, our project also has a no pets policy and very strict about it, this tenant decided to smuggle a cat in, she did kick them out, but now she cannot rent it out no more because of the smell of cat piss, these apartments have laminated floors, maybe she has to have the floor taken up.
On top of that there is damage to the curtains and furniture,
The tenant used to leave the balcony doors open easy for a cat to get to other units, so if they had left their doors open the cat would go into the other units <deleted> and piss there,
The way the building is designed the cat would be able to wonder across 5 different units,
