Hi Crazy4 Cats,
The best you can say is you have to look at the individual foods nutrient profiles and the resulting mix. There is so much “marketing spin” and no consistency across brands in regards to the profiles used for a “senior”food or a “weight loss” food.
What a senior needs is individual to that particular dog or cat. What a dog needs for weight loss is individual to that dog. I tend to not look at what the foods are being marketed as being, and instead look at the product’s nutrient profiles and match to the needs of my dog.
