What a wonderful pile of kitties! There is so much love there, thank you for sharing the pics with us.
Which one of the females is the mother of the kittens? Is it the black and white one with black on the nose? Do the adult female ferals have names yet? They are all so beautiful.
I know it must be hard to have one of the ferals hissing all the time but I'm sure she isn't mean, just scared and protective. Before you came into her life, she probably wasn't treated very well by humans. I hope and pray that in time, she will soften up as she realizes how very kind you are! And hopefully they will stay close to home now that they are spayed and won't be so interested in finding male companionship. They look very happy in those pics and don't look like they're too interested in going anywhere! LOL
If they don't have names, maybe we could help you come up with some!
