whenever I unload groceries from my truck on to the backdoor, I have to shut my furkids inside the house, because they will begin to dig into any meat or dairy products. Also, they instinctively know when I have purchased anything for them, whether it is food (which it usually is, because I buy them something whenever I go to the store whether they need it or not) or toys, or whatever. But , if I leave the paper bags out for any reason, they begin playing with them making a lot of noise. they don't seem to be turned on with the plastic bags, only the paper ones.
