If you want app control and a mid size tank, the PETLIBRO feeder suits a cat owner who checks feeding records remotely. For two cats eating side by side, the oneisall feeder places bowls 16 inches apart to reduce squabbles. Buyers who travel often and want to see their pet should compare the Frienhund camera feeder, while the ANDOLL HOME model keeps setup simple with a 4L tank and voice call. The main tradeoff is connectivity: app models add remote control but cost more, while basic feeders still cover timed meals.

What to Check Before You Buy
A listing tells you only what the maker chose to share. Before you pick an automatic pet feeder, confirm the parts that affect daily use: how many meals you can schedule, how much food the tank holds, and whether it runs on batteries during a power outage. These details are often buried in the feature list, so read past the headline.
For example, the Voluas feeder lets you set 1 to 4 meals daily with 0 to 40 portions per meal, while the PETLIBRO allows up to 10 meals and 48 portions. If your cat needs six small meals, the IMIPAW or oneisall may fit better. If you travel for a week, the Frienhund 7L tank means fewer refills than the IMIPAW 3L.
Also check how the feeder keeps food fresh. Several listings mention desiccant bags or sealing strips, but only some, like the ANDOLL HOME, describe a dedicated desiccant box. The oneisall listing states its stainless steel bowls are dishwasher safe, which matters if you hate hand washing.
Finally, look at the power setup. The ANDOLL HOME uses 3 AA batteries as backup, the Voluas uses 3 D cell batteries, and the IMIPAW also uses 3 D cell batteries. None of these include batteries, so factor that into your cost. The PETLIBRO and Frienhund run on wall power only, though they have app alerts for low battery if you add one.
- Confirm the number of meals and portions per meal.
- Check tank capacity in liters or cups and how often you will refill.
- Look for a desiccant or sealing feature if your home is humid.
- Note the backup battery type and whether it is included.
Capacity and Meal Scheduling Compared
Tank size ranges from 3L to 7L across these six feeders. The IMIPAW 3L is the smallest, holding 12 cups, which the listing says will keep most pets fed for several days. The Frienhund 7L is the largest at 29 cups and can feed multiple pets for weeks. The oneisall 5L holds 20 cups and feeds two adult cats for 10 days.
Meal scheduling also varies. The Voluas feeder allows only 4 meals per day, while the Frienhund allows up to 15 meals. If your cat needs frequent small portions, the Frienhund or PETLIBRO give more flexibility. The ANDOLL HOME listing says 8 meals daily, but the feature text does not state the portion range.
Portion sizes differ in grams. The Voluas portion is 6 to 7 grams, the IMIPAW is 7 to 9 grams, and the oneisall is about 10 grams. The PETLIBRO portion is 1/12 cup, which is roughly 10 grams, but the listing does not give a gram weight. The Frienhund does not state a portion weight in the features.
If you have two cats, the oneisall is the only one that spaces the bowls 16 inches apart to prevent fighting. The Frienhund can feed multiple pets from one bowl, but the listing does not say it prevents one pet from eating all the food.
| Feeder | Tank Capacity | Meals per Day | Portion Size | Backup Power |
|---|---|---|---|---|
| PETLIBRO 5L WiFi | 5L | Up to 10 | 1/12 cup per portion | Not listed |
| Oneisall 5L Two Cat | 5L (20 cups) | Up to 6 | About 10g per portion | Not listed |
| Frienhund 7L Camera | 7L (29 cups) | Up to 15 | Not listed | Not listed |
| ANDOLL HOME 4L | 4L | 8 meals | Not listed | 3 AA batteries (not included) |
| Voluas 4L | 4L (16.9 cups) | 1 to 4 | 6 to 7g per portion | 3 D cell batteries (not included) |
| IMIPAW 3L | 3L (12 cups) | Up to 6 | 7 to 9g per serving | 3 D cell batteries (not included) |
Who Should Skip These Feeders
If your pet eats wet food, none of these feeders will work. Every listing describes dry food only, and the dispensing mechanisms are designed for kibble. A wet food feeder needs ice packs or a refrigerated compartment, which these do not have.
Buyers with very large dogs should also look elsewhere. The oneisall listing says kibble must be under 0.5 inch, and the portion sizes, even at maximum, may not satisfy a 100 pound dog. The Frienhund listing mentions large dogs, but without a stated portion weight, you cannot be sure it dispenses enough.
If you need a feeder that works without any power source, skip these. All of them need either a wall adapter or batteries, and batteries are not included. A gravity feeder might be simpler if you only need a day or two of coverage.
Finally, if your cat is on a prescription diet that requires exact gram weights, the Voluas and IMIPAW list gram portions, but the others do not. The PETLIBRO uses cup fractions, which may be less precise for veterinary needs.
How This Shortlist Was Put Together
The six products here were chosen only from the listing details provided. No units were handled by us, and no in person checks were done. The goal was a spread of designs and sizes, from a 3L basic feeder to a 7L camera model, so you can see what different budgets and needs get you.
Each listing was read for its stated features: tank capacity, meal scheduling, portion size, power backup, and any special functions like cameras or voice recording. The table above compares only what the listings actually state. Where a listing does not state a value, the table says Not listed.
The shortlist includes app controlled feeders, like the PETLIBRO and Frienhund, and button programmed feeders, like the Voluas and IMIPAW. That spread matters because some buyers want remote control while others want a simple LCD screen.

Questions About Picking a Feeder
Do I need WiFi on an automatic pet feeder?
Not necessarily. WiFi lets you change schedules and see feeding records from your phone, which helps if your routine changes often. A basic feeder with buttons and a timer covers set meal times without an internet connection.
How much food should the tank hold for a weekend away?
A 3L tank holds about 12 cups, which most listings say is enough for several days for one cat. For two cats or a week away, a 5L or 7L tank reduces the chance of running out.
Can these feeders handle wet food?
No, these models are for dry kibble only. Wet food needs refrigeration and a different dispensing design, so check the listing before buying if your pet eats canned food.
Which Feeder to Get for Your Situation
A cat owner who wants to check feeding records from the office and set ten meals a day should get the PETLIBRO 5L WiFi Automatic Feeder. Its app control and portion range cover detailed schedules. For a household with two cats that eat at the same time, the oneisall 5L Two Cat Feeder is the better pick because its bowls are spaced 16 inches apart to stop one cat from crowding the other. If you travel for a week and want to see your pet eat, the Frienhund 7L Camera Feeder adds a night vision camera and two way audio, but you pay for those extras.
What this guide is. The picks were chosen by comparing the listing details for tank size, meal scheduling, portion size, power backup, and special features across six different designs. Only listing text was used, and no units were handled, so any performance claims beyond the stated features are not covered.
