For the overwhelmed this Labor Day, you're not alone:
Don't worry, the kittens had a guardian angel (an attentive cat owner) whom, hopefully, has had "Momcat" since fixed:
From the owner of the cat, "I had to do this test. My cat didn't seem fully capable to take care of the kittens. I had to see if she would do the right thing: Take one after the other back in to the basket. But instead she just went to the basket and looked at me for help. As she ended up "saving" none of them, I was never able to leave her home alone. She also sometimes took one of the kittens and wandered off with it, without taking the rest. Afterwards she left it there and went back to the others. The kitten she moved was also at random."
