|Dogs can wolf down an awful lot of food...|
|Cats aren't cheap either...|
Do animals know all this? At a basic level, they do. Not in the way you "know," but in a cellular awareness they understand that they are here in service to planet earth. If you honor them in all three instances, then balance will be the result. Your feelings about their treatment is important. Temper your reactions with the spiritual logic of their appropriateness and their service to humanity. Honor them in all three cases.
