I think a defensless kitten are game to these carnoviourse ,if mamas around its on .The fact Im under the sitiation as Im watching 2 cats at the time for my landlords wife.Its interesting this subject came up.The cat food tub she dropped off is latchable but plastic and one early morning last week it happens that a group of 3 coons where at the cat food container.I watched the mother coon push on the sides of the container as it landed on its side after being wrangled to the porch floor from the table it orig. was on .The 2 small ones lapped up any spilt food from the opening, it was Like a grizzley pushing down on a bear proof container video .I let them work out some of the food but was worried the mother coon would turn on the smaller of the cats so shut down the diner. The tub is now in the cabin but hasnt stopped the coon family coming around.One night my 25lb weiner dog got a face to face at the glass frt door ,the coon wasnt backing dwn so I dont think she would fair well with this encounter.The cats seem to let them move thru without any bother to them but they are little safe crackers.Opened up the screen doors on either side of the screened porch area is the latest activity .One huge owl nest locally AND HAVE seen it fly during a full moon one late night.This is the smaller cats biggest threat ,some lost cat signs are from the flying variety of predator.
