Automatic feeders for two guinea pigs

Guinea pigs on timed pellet portions across two separate cages — that's a specific setup, and it matters that you get it right. The most important things with any automatic feeder are portion accuracy, ease of cleaning, and mechanical reliability. Cheap models jam constantly, drop irregular amounts, and the hoppers are almost impossible to clean, which is a real hygiene problem with small animals. Before I point you in a direction: are both guinea pigs on the same pellet size and daily amount, and how many feeds a day are you aiming for?

Understood — the appeal is obvious, but I want to be straight with you: a single unit physically dispensing into two separate cages isn't really how these devices are designed, and any DIY split-tube setup tends to cause unequal dispensing, which defeats the point. The more reliable and hygienic solution for two guinea pigs is actually two identical compact feeders — they're inexpensive enough that a pair costs less than one premium dog feeder, and you get independent control over each cage. What's driving the preference for one device — is it cost, counter space, or just simplicity of programming?

That makes sense. In that case here's what I'd recommend: two units of the Aqinom Automatic Pet Feeder (the small animal version, widely available on Amazon UK). They're compact, handle pellets reliably without jamming, and the hopper detaches completely for washing — that last point matters a lot with guinea pigs since pellets attract moisture and bacteria quickly. The programming takes about two minutes per unit and you only ever need to set it once unless the schedule changes. Run them both at the same times and same portion — you essentially set one, then mirror it on the second. Ten minutes total, done. The portion wheel is far more consistent than the conveyor-belt style feeders you'll find for a few pounds less.

Jamming is usually caused by two things: pellets that are too small and fall through gaps in the mechanism, or humidity making them swell and stick. Standard guinea pig pellets — the 4–6mm size most brands use — work well in the Aqinom's rotor design. The bigger risk is moisture buildup in the hopper if it's near a water bottle or in a humid room. Keep the feeder positioned away from any drinking spouts, don't overfill the hopper, and give the removable parts a rinse every two weeks. Do that and you'll have very few problems.

Good call. Search 'Aqinom automatic pet feeder small animal' on Amazon UK and you'll find them — check you're getting the version with the detachable hopper rather than the older sealed design. Set them both up a few days before you actually need them so you can watch a couple of cycles and confirm the portions look right. Twenty grams twice a day is well within the reliable range for that feeder. Your guinea pigs will be fine.
