Never Run Out of Pet Food, Litter or Medication
Running out of pet food on a Sunday evening is annoying. Running out of a daily prescription is a real problem. A few numbers — how much you use and how long a refill takes — are all you need to stop it happening.

Work out how long things last
| Supply | How to estimate | Example |
|---|---|---|
| Dry food | Bag weight ÷ daily portion | 12 kg ÷ 300 g/day ≈ 40 days |
| Wet food | Units ÷ units per day | 24 pouches ÷ 2/day = 12 days |
| Cat litter | Observe one full bag, note the days | 10 L lasts ~14 days for one cat |
| Tablets | Count ÷ tablets per day | 30 ÷ 1 = 30 days |
| Parasite prevention | Doses in pack × interval | 3 monthly doses = 3 months |
Set the threshold by lead time, not by feel
The reminder should fire when the remaining supply equals the time it takes to get more — plus a buffer.
- Online food order: delivery 3–5 days + 3 days buffer → reorder with about a week left.
- Prescription medication: the vet may need to authorise a repeat, and some need a recheck first → reorder with at least 10–14 days left.
- Specialist diets are often out of stock locally → keep a bigger buffer.
In PetCare Offline you can track supplies such as food, litter, medicine and treats with a low-stock threshold, and set refill reminders alongside the pet's other care.
Medication refills need extra care
- Set the refill reminder when you collect the medication, not when it is nearly gone.
- Note whether the prescription needs a recheck exam before renewal — many long-term medications do.
- Keep a copy of the prescription as a document in the pet's profile.
- Never stretch doses to make a pack last longer; call your vet if you are about to run out.
Travel buffer: before a trip, make sure you have the whole trip's supply plus a few extra days of food and every medication. Delays happen, and some products are hard to find away from home.
A monthly two-minute check
- Glance at the supplies list and adjust amounts if the pet's portion changed.
- Check expiry dates on medication and first aid items.
- Update thresholds if a supplier's delivery time changed.
Changing food
If you are switching food, order the new one early: most vets recommend a gradual transition over about a week, which means you need both foods at once for a while. See dog feeding schedule for portions and timing.
Frequently asked questions
When should I reorder pet medication?
With at least 10–14 days left, because refills may need vet authorisation or a recheck exam. Set the reminder when you pick up the current supply.
How do I know when a bag of pet food will run out?
Divide the bag weight by the daily portion. A 12 kg bag at 300 g a day lasts about 40 days; set the reminder for about a week before that.
Can PetCare Offline track supplies?
Yes. You can track food, litter, medicine and treats with low-stock thresholds and set supply refill reminders.
