southsamurai has a great overall explanation. I would add it also depends on the age and any medical conditions of each.
We have a 45 pound dog (age 12) and a 15 pound cat (age 17). The dog is on senior/old man food but is otherwise in good health. The cat has kidney disease so we have to get only specific kinds. Per month the cat’s food is about $5 more than the dog’s, but that’s for a smaller amount.
