I know yaar.
I just feel sorry for other peoples cats/dogs, they have dull eyes and coats and their rib cages show, clear signs of malnutrition.
Vegetables/grains just don't contain all the essential amino acids to make up protein, whilst meat, poultry, fish and eggs do. It's like the pieces of a jigsaw puzzle.
Even humans who are omnivores need meat, and cats/dogs are carnivores..
