Yes, the RER formula (70 × weight^0.75) is a standard reference point used in veterinary nutrition, though individual needs vary.
Does this account for spaying/neutering?
The 'typical adult, neutered' option reflects a commonly used activity factor for that group.
Should I adjust my pet's food based on this alone?
