If you have a cat and a dog indoors, then you have probably caught them stealing each otherâ€™s food once in awhile. For both animals, a little snack from the otherâ€™s food bowl is not a big deal.

So, before you overlook your pooch eating from the catâ€™s bowl, there are a few things to consider. If the habit has already started, then you need to work on ways to stop it.
