OMG! Those poor babies.
It kills me to see that. I just want to come get them and bring them home. Are you sure they are all feral? Any chance they are strays?
Do you have a no kill or rescue around? How about a t/n/r group that would help with them? Any chance hubby could make a little shelter thing for them so they can get out of the cold wind??
I really feel for you Di. I know how difficult it is to see that.
