Goodness gracious, they're just adorable and so lucky that you found them. They may have been in different places because the mom may have been hiding them. I experienced this years ago when I was in rescue. One feral mom hid her kittens all over the place and I was trying to find them because I had been treating their eyes, which were nasty and crusted. Mom would have no more of it and it was a couple of weeks before she brought them all back. Lovin' the name Nom Noms. Thank you so much for taking care of these little sweetie pies.
