The quick answer
Divide the feeder’s capacity in cups by your pet’s daily portion. One liter holds roughly 4.2 cups of kibble, so a 4L feeder holds about 17 cups and a 12L feeder about 50. Most cats do well with 4–6L; larger dogs or longer refill gaps call for 11–12L.
Step 1: Find your pet’s daily portion
Start with the feeding guide on your pet food bag, which is usually given in cups per day by weight. Your veterinarian may recommend a different amount based on age, activity and body condition, so their advice comes first.
Write down the total daily amount, not the per-meal amount. If your cat eats ¼ cup twice a day, the daily portion is ½ cup.
Step 2: Convert liters to cups
One liter is about 4.2 U.S. cups. Kibble doesn’t pack perfectly, and dense, small kibble fits more into the same space than large, airy pieces, so treat these as estimates.
- 4L (Parveja Twin): about 17 cups
- 6L (Parveja Keeper): about 25 cups
- 11L (Parveja Ranger): about 46 cups
- 12L (Parveja Titan): about 50 cups, roughly 50 cups of dry food
Step 3: Decide how often you want to refill
Divide the cups by the daily portion to get the number of days a full tank lasts. Then think about freshness: the longer kibble sits in a feeder, the more it’s exposed to air and humidity. Many owners prefer to refill more often than the maximum so food doesn’t sit too long. Follow your pet food’s own storage guidance.
Storage helps. Twin comes with desiccant packs, Keeper’s tinted container helps shield food from light, Ranger’s tank is sealed, and Titan closes its outlet between meals.
Which size suits cats?
Most adult cats eat well under a cup a day, so even a 4L feeder lasts a long time between refills. For one cat, a 6L feeder like Keeper keeps food turning over. For two cats, Twin’s 4L tank fills two bowls at once. Choose a larger size only if you want fewer refills and can keep the food fresh.
Which size suits dogs?
Dogs vary enormously. A small dog might eat a cup a day, while a large breed can eat four or more. For medium and large dogs, an 11L or 12L feeder avoids refilling every few days. Check the kibble size too: large-breed kibble can be big, so contact us to confirm your dog’s food before ordering.
Capacity isn’t the only thing to compare
Once you know the size range you need, compare the features that affect daily life: a camera for checking in, backup power for outages, how many meals per day you can schedule, and how easy the bowl and tank are to clean.
- Every Parveja feeder has a 1080p camera with night vision.
- Want the most meal flexibility? Keeper schedules up to 15 meals a day.
- Feeding two cats? Twin (4L) fills two bowls at once, from $199.
- Large breed? Titan (12L) adds two-way audio and low-food alerts.
Approximate days per full tank
| Feeder size | ≈ Cups | ½ cup/day | 1 cup/day | 2 cups/day | 4 cups/day |
|---|---|---|---|---|---|
| 4L (Twin) | ~17 | ~34 days | ~17 days | ~8 days | ~4 days |
| 6L (Keeper) | ~25 | ~50 days | ~25 days | ~12 days | ~6 days |
| 11L (Ranger) | ~46 | ~92 days | ~46 days | ~23 days | ~11 days |
| 12L (Titan) | ~50 | ~100 days | ~50 days | ~25 days | ~12 days |
Estimates only. Actual capacity depends on kibble size and density. Refill more often than the maximum to keep food fresh, and follow your pet food’s storage guidance.
