Is RER the same as the calories on my food bag?

Food labels show kcal per cup or per can. This calculator estimates how many total kcal your pet may need per day so you can compare portions to the label.

Why use 70 times weight to the 0.75?

It is a widely taught exponential form for metabolic size scaling in dogs and cats. Your clinic may use a slightly different reference.

My pet needs to lose weight. Should I use MER from this tool?

Weight loss plans often use a reduced percentage of current or ideal maintenance calories. Ask your veterinarian for a safe deficit.

Does activity level matter for an indoor cat?

Yes, but many indoor cats are closer to sedentary unless you add structured play. Your veterinarian can help classify activity.

Are puppies and kittens covered?

Growing animals have higher needs per kg than adults. This adult-oriented model is not meant for growth life stages.

Can I use pounds instead of kg?

Convert pounds to kg first (divide pounds by about 2.20462), then enter kg for this tool.
