An a86 automatic pet feeder can take the daily feeding routine off your plate, but only if it is set up correctly from the start. This guide walks you through unboxing and placement, bowl and food preparation, scheduling, portion sizing, and a short daily check so your pet gets consistent meals even when you are out of the house. Because the a86 is one of many budget-friendly timed feeders on the market, the steps here are written to apply to general timed-feeder design, so you can confirm details against the manual that ships with your unit.

What You Need Before You Start

Gather these items before you power anything on. Having everything ready prevents the most common first-week problems, like a feeder set to the wrong time or a bowl that does not fit the mechanism.

Shopping for one? See our guide: 4 Best Automatic Pet Feeder PetSafe Models Compared (2026).

  • The feeder unit with its lid, food bowl or tray, and power adapter
  • Batteries (if the model takes them) or a nearby outlet
  • A measuring cup or kitchen scale for dry food
  • Your pet’s current food, plus the feeding amount your veterinarian recommended
  • A flat, stable surface close to a power source and away from direct sunlight
  • A small brush or dry cloth for cleaning the dispensing area

Step 1: Choose the Right Location

Placement affects both food quality and how reliably the feeder runs. Put the unit on a level, hard floor such as tile, vinyl or sealed wood. Carpet can cause the base to rock, which may interfere with the dispensing mechanism and make the feeder seem faulty.

Keep it out of direct sunlight and away from heating vents, since heat can clump dry kibble and attract pests. Stay at least a few feet from water bowls so splashes do not reach the food compartment. Also consider your pet’s behavior: some cats and dogs will guard or repeatedly paw at a feeder placed in a busy hallway, so a quieter corner often works better.

Step 2: Prepare the Food Compartment

Start with a clean, completely dry food container. Residual moisture from washing can cause kibble to stick to the walls and jam the dispenser. Wipe the inside with a dry cloth and let it air-dry if you washed it.

Fill the compartment with dry food only. Most timed feeders are designed for kibble, not wet food, canned food, or treats with a high fat content, because these can stick to the auger or chute. If you are switching foods, transition gradually over several days rather than swapping everything at once. Your veterinarian can advise on a transition schedule for your pet’s specific needs.

Step 3: Set the Clock and Power Up

Install batteries or connect the power adapter, then set the current time and day before programming any meals. A wrong clock is the single most common reason a feeder seems to dispense at odd hours. Check the time once a week, especially after a power outage or battery change, since some units reset their clock when power is interrupted.

Once the clock is correct, run a test cycle using the manual feed button if your model has one. Confirm that food drops into the bowl cleanly and that the mechanism stops when it should.

Step 4: Program Your Meal Schedule

Most timed feeders let you set several meals per day. Plan around your pet’s normal routine and the times you are typically home. For many adult dogs, two meals spaced about 8 to 10 hours apart works well, while many adult cats do better with several smaller portions. Your veterinarian can recommend a schedule suited to your pet’s age, weight and health.

Sub-steps for Scheduling

  1. Select the meal slot you want to program (usually labeled 1, 2, 3 and so on).
  2. Set the hour and minute, using AM and PM carefully if your display uses them.
  3. Enter the portion size for that slot.
  4. Confirm each slot and check the display to make sure it saved.
  5. Leave at least a few minutes between slots so one feeding cycle finishes before the next begins.

Step 5: Set Accurate Portion Sizes

Portion settings usually count in grams or in dispenser “units,” and the unit size varies between models. Because of this, do not assume one unit equals one gram. Run a test: dispense one portion, weigh the food in the bowl, and adjust until the amount matches your target.

Step What to Do Why It Matters
Calibrate Dispense one test portion and weigh it Shows how many grams one setting delivers
Adjust Increase or decrease the setting and retest Matches the amount to your pet’s daily need
Divide Split the total daily amount across meal slots Keeps total intake consistent
Verify Check the bowl after the first full day Confirms the schedule works in practice

Start with the daily total recommended on your pet food bag or by your veterinarian, then divide it among your meal slots. Keep in mind that treats and table scraps count toward daily calories, so reduce meal portions if you give them regularly.

Step 6: Watch the First Few Days

Observe closely during the first three to five days. Look for food left uneaten, which may mean the portion is too large or your pet is not yet adjusted to the new routine. Check whether your pet is gaining, losing or holding steady weight, and adjust portions gradually if needed. Some pets are wary of a new mechanical sound, so expect a short adjustment period.

Common Mistakes

  • Loading wet or sticky food. This is the most frequent cause of jams. Stick to dry kibble unless the manual says otherwise.
  • Trusting the display without testing. Always weigh a test portion before relying on a setting.
  • Forgetting the clock after a power outage. Check the time after any interruption to avoid missed or early meals.
  • Overfilling the hopper. A crowded compartment can jam the auger. Fill to the level the manual indicates.
  • Placing the feeder on an uneven surface. A rocking base can misfire or drop food unevenly.
  • Ignoring food freshness. Kibble left in a warm feeder for days can lose flavor and nutrients. Refill with fresh food regularly.

Tips for Daily Use

  • Clean the bowl and dispensing area at least once a week to prevent buildup and odors.
  • Keep a spare set of batteries on hand so an outage does not cause a missed meal.
  • Write your schedule and portion settings on a card near the feeder so anyone pet-sitting can follow them.
  • If your pet is a fast eater, a slow-feed bowl insert can help prevent gulping.
  • Test the feeder before any trip, and arrange for someone to check on your pet if you are away for longer than a single day.

A few simple accessories can make the daily routine smoother. A kitchen scale helps with the portion calibration in Step 5, since a gram-accurate reading is far more reliable than estimating with a scoop. A slow-feed insert suits pets that eat too quickly. A set of spare batteries prevents missed meals during outages. A dry-food storage container with an airtight lid keeps kibble fresh between refills.

FAQ

How long can an automatic pet feeder go without refilling?

It depends on the hopper capacity and your pet’s daily portion. Divide the container’s total volume or weight by the daily amount to estimate how many days it will last, then refill with a small margin to spare.

Can I use wet food in an a86 automatic pet feeder?

Most timed feeders are designed for dry kibble. Wet food can stick to the mechanism and cause jams, so check the manual before using anything other than dry food.

What should I do if the feeder dispenses at the wrong time?

First check that the clock is set correctly, including AM and PM. Then confirm each meal slot was saved. If the problem continues, reset the unit according to its manual.

How do I know if the portion size is right?

Weigh a test portion, compare it to your target amount, and monitor your pet’s body condition and weight over several weeks. Adjust in small steps and check with your veterinarian if you notice weight changes.

Is it safe to leave my pet alone with an automatic feeder?

Feeders can be a reasonable part of a routine, but pets with medical conditions, such as diabetes or a history of gastrointestinal issues, need carefully planned feeding. Consult a veterinarian before relying on a feeder for any pet with a health condition.

How often should I clean the feeder?

A weekly wipe-down of the bowl and dispensing area is a good baseline. Clean more often in humid conditions or if you notice odors or residue.

Why is my pet not eating from the feeder?

Some pets need time to adjust to a new mechanism or location. Try placing a small amount of food by hand next to the feeder, and make sure the portion is not too large. If your pet continues to refuse food for more than a day, contact your veterinarian.

Can I feed treats through the feeder?

Treats generally should not go through the feeder, since they can clog the mechanism. Give treats by hand and reduce meal portions to account for the extra calories.

Conclusion

A well-set-up a86 automatic pet feeder can keep meals on schedule and reduce the stress of busy days. Choose a stable location, load only dry food, set the clock first, and calibrate portions by weighing a test serving. Watch your pet closely for the first few days, and adjust as needed with guidance from your veterinarian.
