I spoke to the leasing manager yesterday. Turns out this is something the new property manager did while she was away. I have had run ins with this new manager about other things in the past. The leasing manager is a kind woman who was sincerely concerned when I told her what will happen to them at a shelter, but it is not her I need to convince. She is going to have the other woman contact me Monday with the contact info of the person doing the trapping. Apparently they are from the department of natural resources.
Baltimore has a TNR law in place and maybe if I can show him I am their registered caregiver he will back off. The other option is that through a Craigslist post asking for help and through emailing the local version of ally cat allies, a lawyer contacted me last night. I am going to call her in a minute but it is a delicate situation I cannot irk the management too much as I live here and I don't want them saying that as the caregiver the cats are mine and thus am breaking the lease. :/
