By Ethan BrooksAn automatic pet feeder can take the guesswork out of mealtimes, delivering measured portions on a schedule even when you are at work, running late, or away for the weekend. If you are looking at an automatic pet feeder at PetSmart, this guide walks you through what to check before you buy, how to match the feeder to your pet’s routine, how to set it up, and what to avoid once it is running. By the end, you should be able to choose a model confidently and start a feeding schedule that fits your household.
What an Automatic Pet Feeder Does (and What It Does Not)
A timed feeder is a container with a motorized dispenser that releases food at times you program. Most models hold dry kibble only, and a smaller group handles wet food with extra refrigeration or a plate design. The feeder does not monitor how much your pet actually eats, and it cannot tell whether a pet is sick. Think of it as a reliable clock-driven scoop, not a substitute for watching your pet’s appetite and body condition.

Feeders are most useful for cats and dogs on consistent meal schedules, for households where meals are often missed, and for multi-pet homes where one animal needs a controlled portion. They are less useful for pets that need frequent small meals, pets on prescription diets that require exact handling, or animals that eat grazing-style and have no set schedule.
Step 1: Confirm the Feeder Fits Your Pet and Food
Before comparing features, check three basics: the food type, the kibble size, and the portion range.
- Kibble size: Measure a few pieces with a ruler. Many dispensers list a maximum kibble diameter, often in the range of about 1 inch. Oversized or irregular pieces can jam the auction or hopper.
- Portion increment: Smaller pets need finer control. A feeder that releases in large steps may be too coarse for a 6-pound cat.
- Container capacity: A larger hopper means fewer refills but more food sitting in the open. Measure how many days of food you need to hold.
- Pet size and behavior: Large dogs may need a sturdier bowl that resists tipping. Cats that paw at moving parts may need a locking lid or a feeder with a sealed mechanism.
Step 2: Compare the Features That Affect Daily Use
Once you know the basics fit, compare the features that determine how the feeder performs over months, not just on day one.
| Feature | Why it matters | What to look for |
|---|---|---|
| Programming | Determines how easily you can change schedules | Buttons with a clear display, or a companion app if you prefer phone control |
| Power backup | Keeps meals on time during a short outage | Battery compartment or backup battery option; check battery type |
| Food seal | Protects kibble from humidity and pests | Airtight or gasketed lid |
| Cleaning access | Hard-to-clean areas grow residue and odor | Removable hopper, wide opening, dishwasher-safe parts where stated |
| Portion control | Prevents overfeeding and gaps in meals | Adjustable portion settings with a stated range |
Read the manufacturer’s stated specifications for capacity, portion range, and power source rather than relying on general impressions. If you want a sense of how a specific model works in practice, many owners share detailed reviews. For example, if you are comparing the Pitpet line, you can read Pitpet Automatic Pet Feeder Review: Is It Worth It? for a closer look at what owners report.
Check Power Options Before You Buy
Some feeders run on AC power with battery backup, while others are battery-only. Battery-only units are convenient for placement but need regular replacement. Confirm the battery type and the stated number of meals per set before assuming you will be covered during a storm or a power cut.
Think About Wi-Fi and App Features
Smart feeders with app control can send feeding alerts, let you dispense a treat remotely, or record how often the feeder opens. These features are useful for owners who travel, but they add setup steps and depend on a stable home network. A basic button-programmed feeder is often enough for a predictable routine.
Step 3: Set Up the Feeder Correctly
Setup mistakes account for most early frustration. Follow these steps in order.
- Unpack the feeder and check the parts against the manual. Confirm the hopper, bowl, lid, and power adapter are present.
- Place the feeder on a flat, stable surface away from direct sun, heaters, and damp areas.
- Install batteries if required, using the type the manufacturer specifies.
- Fill the hopper with dry food only. Do not add wet food unless the model is designed for it.
- Run a test dispense with the lid open over a container to confirm the food flows and the mechanism turns freely.
- Program the clock first, then the feeding times. Check the time zone and AM/PM settings.
- Set portion sizes, starting with the amount your veterinarian or the food label recommends for your pet’s weight.
- Let your pet approach the feeder for a few days with a bowl in front of you so the animal learns the sound and the food source.
Set Portions Carefully
Start with the guideline on your pet food bag, then adjust based on body condition. Your vet can confirm an ideal weight and daily calorie target. Feeders often measure in grams or cups, so convert carefully. A small mismatch repeated twice a day adds up over a month.
Step 4: Run a Trial Week and Adjust
During the first week, check the bowl at each scheduled time. If the feeder is accurate, the bowl should be empty or nearly empty by the next meal in most cases, and you should see steady eating rather than food piling up. Watch for three signs that the setup needs changing:
- Food left in the bowl for more than a few hours suggests the portion is too large.
- Your pet seems hungry or vocal between meals suggests the portion is too small or the schedule is too spread out.
- Kibble jams or dribbles out irregularly suggests the kibble size or moisture is wrong for the feeder.
Adjust one variable at a time so you know which change made the difference.
Common Mistakes to Avoid
- Loading wet food into a dry-food feeder. It can spoil, clog the mechanism, and attract pests.
- Skipping the test dispense. A jam discovered at 6 a.m. is harder to fix than one found during setup.
- Assuming the default portion is correct. Factory settings are not tailored to your pet.
- Letting the hopper sit unrefilled for too long. Check the food level weekly and keep the seal closed.
- Forgetting to clean. Residue and fat build up in the chute and bowl. Clean on a fixed schedule, such as weekly.
- Relying on the feeder alone for health monitoring. Weigh your pet regularly and watch for changes in appetite.
Recommended gear
These items support a feeder setup but are not required. Choose based on your home layout and your pet’s habits.
- A small kitchen scale. Helpful for converting food bag guidelines into the exact grams a feeder needs. View on Amazon
- A washable silicone mat. Catches spilled kibble around the bowl and makes cleanup faster. View on Amazon
- A stainless steel cleaning brush set. Reaches into narrow chutes and bowl corners that sponges miss. View on Amazon
- A sealed food storage container. Keeps the reserve kibble fresh between hopper refills. View on Amazon
Tips for Long-Term Success
- Keep a simple log for the first two weeks noting what time the bowl empties and any changes in behavior.
- Adjust portions for seasonal activity. Outdoor cats and active dogs may need more on busy weeks.
- Store a backup manual or the model number so you can troubleshoot without searching for the paperwork.
- If you are weighing several models, look at setup guides and troubleshooting notes from owners. For instance, Pitpet Automatic Pet Feeder Manual: Setup, Programming and Troubleshooting Steps covers the kinds of issues that come up after unboxing.
- When comparing many options at once, a roundup helps. Westlink Automatic Pet Feeder: 9 Best Picks for Every Routine (2026) and Wirecutter Automatic Pet Feeder: 10 Best Picks Compared in 2026 show how different designs stack up across routines.

FAQ
Can I use an automatic pet feeder at PetSmart for wet food?
Most standard dispensers are designed for dry kibble only. Wet food spoils quickly at room temperature and can clog the mechanism. Look for a model explicitly labeled for wet food, and follow the manufacturer’s guidance on refrigeration and discard times.
How many meals can a feeder hold?
This depends on the model’s stated capacity and the portion size you set. Divide the hopper’s rated volume by your daily portion to estimate how many days the food will last. Leave a margin, and refill before the hopper runs low.
What happens if the power goes out?
Models with battery backup usually keep the clock and schedule running during a short outage. Check the manual for the backup battery type and how long it is expected to last. Battery-only models rely entirely on battery life.
How do I know if the portion is right?
Watch the bowl between meals and track your pet’s weight and body condition. A bowl that is consistently empty well before the next meal, or a pet that looks thinner, suggests the portion may need adjusting. Confirm changes with your veterinarian.
Will my cat or dog learn to use the feeder?
Most pets adjust within a few days, especially when you place a familiar bowl nearby during the first meals. Some animals take longer, so be patient and avoid forcing the issue. If a pet refuses to eat from the feeder after a reasonable period, consult your veterinarian to rule out a health issue.
How often should I clean the feeder?
Wipe the bowl and chute at least weekly, and wash the hopper and any removable parts according to the manufacturer’s instructions. Dry all parts fully before refilling to prevent mold and odor.
Is an automatic feeder safe for pets with medical conditions?
Pets on prescription diets, insulin, or other medically managed feeding plans should only use a feeder after discussing the plan with a veterinarian. Medical feeding needs often require precise timing and portions that a general-purpose feeder may not deliver reliably.
Do automatic feeders work for multiple pets?
Some models have a single bowl and are better for one pet. Multi-pet households often need a feeder with separate compartments or a way to block other animals from the bowl. Check the product specifications before assuming a single unit will work for two or more pets.
Conclusion
A well-chosen automatic pet feeder can keep mealtimes steady, even on busy days. Start by matching the feeder to your pet’s size, food type, and kibble size, then set portions carefully and run a trial week. Adjust one setting at a time, and keep an eye on your pet’s weight and appetite. If your pet has a health condition, check with your veterinarian before relying on any automated schedule.
