Cats being shot with BB gun in Kansas City!

I have posted this on two feral cat groups I belong to and only one person replied. That is disappointing.

I volunteer with a woman who told me that someone she works with has seen cats being shot with a BB gun as a means to control the population.

1. That does not work
2. That is inhumane!

The man who lives there has told either the maintenance man or the manager that he does not believe that is the right thing to do. The woman who told me about this couldn't remember which one he said was shooting them.

BB guns maim cats-not kill them. So, they will live awhile. They will be walking around, wounded and in pain and die a slow, agonizing death.

I am not sure what to do besides call the apartment complex and let someone there know that I know what is happening and I am a feral cat rescuer. I want to put some pressure on them. This is their problem but people will be watching how they handle it.

Anyone have any ideas on what I could do? Has anyone dealt with this type of situation before?
