The numbers behind everyday pet care
Owning a dog or cat comes with more math than most people expect. Before you bring one home, the monthly cost calculator shows the real ongoing price of food, vet care, insurance and grooming. Once they're home, the food portion calculator uses the same RER/MER formula vets use to work out exactly how much to feed — and the vaccine schedule keeps their core shots on track. And for fun, the age calculator tells you how old they'd be if they were a person.
