Pet Emergency Kit Calculator
Pet go bag food, water, and jugs for dogs and cats by days.
What it does
Evacuations include paws. A counted pet kit keeps dogs and cats fed and watered when stores close and routines break.
The tool above feeds a pound per dog and a quarter per cat daily. One dog and two cats for three days need 4.5 lb of food with 2.25 gal of water in 3 jugs. The metric match is 2 kg with 8.5 L.
Water runs the kit. A quarter gallon per pet per day covers drinking plus a margin for spills and heat.
Jugs round the plan up. Whole sealed jugs travel cleaner than open bowls, with one spare past the math.
Gear rides along. Leashes, carriers, meds, and vaccine records matter as much as kibble at shelters.

Worked example
Example: 1 dog, 2 cats, 3 days
Defaults: 1 dog, 2 cats, 3 days. These are also the default values, so the page opens on this answer.
- Pets: 1 dog and 2 cats.
- Days: 3.
- Food: (1 x 1 + 2 x 0.25) x 3 = 4.5 lb.
- Water: (1 + 2) x 0.25 x 3 = 2.25 gal.
- Jugs: ceil(2.25) = 3 jugs.
- Tool shows 4.5 lb food, 2.25 gal water, 3 jugs (1 gal).

Try it yourself
Quick checks. Answers sit tucked under each question.
2 dogs, 5 days?
Food is (2 x 1 + 0) x 5 = 10 lb. Water is 2 x 0.25 x 5 = 2.5 gal. Jugs are ceil(2.5) = 3 jugs.
4 cats, 7 days?
Food is (0 + 4 x 0.25) x 7 = 7 lb. Water is 4 x 0.25 x 7 = 7 gal.
Questions
Food needed?
Add a pound per dog plus a quarter per cat, times days. Here (1 + 0.5) x 3 = 4.5 lb.
Water needed?
Quarter gallon per pet per day. Here 3 x 0.25 x 3 = 2.25 gal.
Jugs?
Round water up to whole jugs. Here ceil(2.25) = 3 jugs.
Dry or wet food?
Rotate kibble before dates and seal against pests. Wet food adds water but weighs more.
Gear too?
Yes. Leashes, carriers, meds, and vaccine records ride with the kit.
Prescription diets included?
No. Special diets need vet sized kits.
