x2… that extra $25/ month pet fee is supposed to be used to handle any normal wear that a pet would cause to the dwelling. obviously if you have a rotweiller thats eating holes in the walls and chewing up the corners of doors its not gonna cut it, but i cant imagine a couple cats causing that much drama.
I think you are well within your right to send him that letter and get your money back. If he doesnt have time to handle all his properties according to the law then perhaps its time to hire a property manager!
