I think it's okay...sorta.
When she carried that large green bucket/bowl in there I was concerned about how all of the cats would be sure to get enough food; bold would out-eat the more timid. I had thought to myself, why doesn't she scatter it on the tile floor?
However, I wouldn't scatter handfuls like chicken feed, I'd try to pour out rough concentric circles. At least with scattering it, all of the cats are assured of finding morsels.
My only hope is that they are spayed/neutered and not creating more and MORE cats that have to eat what she can afford to give. They will quickly outgrow her ability to give, if that is the case.
