Pet Care Math: the big picture
Pets come with small recurring numbers that add up: portions per meal, litter per month, age in human terms, and the annual cost of care. BoringToolsKit's pet calculators turn those into a budget you can plan around.
- Dog and cat food portions are based on weight and activity.
- Cat age conversion is roughly 15 human years for the first year.
- Annual pet cost includes food, litter, vet care, and supplies.
