Pet Care Tools
These tools help with the routine side of owning a dog, cat, rabbit or other small pet: how old it is in human terms, how much to feed it, whether its weight is drifting, what it costs over its life, when the next treatment is due, and what to call it. They suit new owners, people adopting an older animal and households sharing care.

Which tool do I need?
Find out how old my dog or cat is in human years
Enter age in years or months to get a human-equivalent age and life stage; for giant breeds read it as a minimum.
Work out how much to feed each day
Turn weight, life stage, activity and food type into daily kcal, grams and grams per meal, with the RER shown.
Keep a weight log to show the vet
Record dated weigh-ins, see the trend against an ideal weight and export a CSV before the appointment.
Budget for a new pet before adopting
List food, insurance, grooming and one-time costs to get monthly, yearly and lifetime estimates.
Keep track of flea treatments, vaccinations and vet visits
Add dated tasks and see what is overdue or due in the next seven days; add the next date yourself after each one.
Choose a name the family agrees on
Generate ten names at a time by pet type and style, star favourites and copy the shortlist to share.
About Pet Care
The calculators feed each other. The Pet Age Calculator uses the curve vets often quote for dogs and cats (15 human years for the first year, 9 more for the second, then 5 a year for a dog or 4 for a cat) and names the life stage. That matters because the Pet Feeding Calculator multiplies resting energy, 70 x weight in kg to the power 0.75, by a life-stage factor. Feed for ideal weight, then log progress in the Pet Weight Tracker, which charts weigh-ins and exports CSV for your vet. The Pet Expense Calculator converts recurring costs into monthly and yearly totals and projects them over a typical lifespan, and the Pet Care Reminder sorts tasks into overdue, upcoming and later.
Limits: age and feeding figures for rabbits, hamsters and birds are much rougher than for dogs and cats, and neither calculator asks for breed or size, which changes how fast a dog ages. Gram amounts assume a typical energy density, so dividing the kcal figure by the kcal on your food bag is more reliable. The reminder sends no notifications and does not roll recurring dates forward. Records stay in this browser only, and none of this is veterinary advice.

Frequently asked questions
What records should a pet owner keep for the vet?
Weight over time, vaccination and parasite treatment dates, medications with doses, and any changes in appetite or behaviour. Dated weigh-ins are the record owners most often lack, and a CSV from the weight tracker gives the vet a trend instead of a single number.
Do the pet tools work for rabbits, hamsters and birds?
Partly. The age and feeding calculators include rabbits, hamsters and small birds but use single rough multipliers for them, so treat the results loosely. The weight tracker, expense calculator, reminders and name generator work for any species.
Can two people in a household share pet records?
Not directly. Records are stored in the browser where they were entered, so another person's phone will not see them. Share the weight tracker's CSV export, or keep one device as the household record for reminders and expenses.
Which pet tool should I use first after adopting an animal?
The feeding calculator, since the right daily amount depends on age, weight and life stage. Then start a weight log at the first vet visit and add vaccination and parasite treatment dates to the reminder list. The expense calculator is most useful before you adopt.
Why might pet age and feeding estimates differ from my vet's advice?
Because the calculators use general formulas and cannot see your animal. Breed, size, neutering, body condition and health all change the right answer. Use the numbers to start the conversation and follow the vet when they differ.
