5L/21 Cup Automatic Cat Feeder - Timed Pet Food Dispenser for Up to 6

In this review the DUDUPET 5L/21 Cup Automatic Cat Feeder is presented as a practical solution for pet owners who need reliable, scheduled feeding without daily refills. The single biggest reason to buy is its large 5L capacity combined with programmable portions, which means one device can feed multiple small meals across several days while the owner is away. Setup and daily use are straightforward, and the sealed, lockable container plus desiccant box keeps dry kibble fresher-making this model a sensible choice for families, busy professionals, and multi-pet households.

Key Features

• Spacious 5L food storage: The large 1.3 gallon container holds up to 21 cups of dry food so pets are fed for days without refilling.
• Programmable timed feeding: You can schedule up to 16 meals per day with up to 120 portions each to match different ages and portion needs.
• Adjustable portion size: Portion control allows consistent servings for weight management and accommodates a range of pellet sizes.
• Dual power supply: The feeder runs on the included 5V DC adapter and 3 D-cell batteries as backup to keep the schedule during outages.
• Hygienic and easy to clean: Food-contact parts detach for simple washing to keep the dispenser sanitary.
• Anti-jam dispensing and sealed freshness: Built-in anti-jam rotor and desiccant box help deliver accurate portions and preserve kibble crispness.

Who It's For

This feeder is ideal for cat and small puppy owners who need a dependable automatic feeder for travel, long workdays, or multi-pet feeding. Homes that prefer scheduled, smaller meals for weight control or consistent routines will get the most value from the programmable 16-meal, 120-portion system.

Owners of very large-breed dogs or households that require wet food options should look elsewhere, since this model is designed for dry kibble only and lists suitable pellet sizes between 0.07 and 0.55 in. If precise wet food handling or much larger kibble is required, consider a different feeder type.
