Were you not planning on feeding the new bag right away? Still finishing up a previous bag of kibble? Taping it up and getting the most air out of the packaging as possible while it is being stored is a good idea. Having the package opened whether by cat or by opening to feed it has the same outcome. Since the bag is opened, it should be used as soon as possible. Some sites suggest using a bag of kibble within 3 weeks of opening.
