Well, the kittens got to stretch their legs tonight on the porch, and they attracted lots of attention from the dogs, partially because they had just snacked on some soft tuna cat food.
They are used to the dogs being around, and they didn't seem to mind the attention.
We have been keeping them in a cage on the porch, because mama cat Gracie, as moved them twice to the neighbors about 300 yards away, where we have retrieved them twice!
