@roger,
You forgot one step. You need to give them all names.

NO no no no hell no....The last outside cat that my wife name after I told her not to is sleeping on the living room couch at the moment.
It bad enough that they are in the outside enclosed porch.
I am down t0 three indoor cats and plan to get down to one cat in the future so mom is going back outside and the kittens will be name by their new human families not by me.
