Quick Answer: What Are the Best Low-Maintenance Pets?
The best low-maintenance pets are invertebrates - isopods, springtails and millipedes. They fit on a shelf, cost very little to run, need feeding only occasionally, are silent and odourless, and largely look after themselves once set up. Beyond the inverts, betta fish and African dwarf frogs are the easiest of the aquatic options, and leopard geckos the most forgiving reptile, though each needs more space, kit or long-term commitment. If minimal effort and minimal space are your priorities, invertebrates are unbeatable - and they're exactly what we keep and sell here at PostPods.
What "Low-Maintenance" Actually Means
One honest caveat up front: low-maintenance doesn't mean no-maintenance. Every pet needs a proper initial setup, the right food and regular basic cleaning. The difference is how often and how long - minutes a week rather than hours a day. By "low-maintenance" we mean a pet that needs only a few minutes of attention most days, feeding anywhere from daily to weekly, and a habitat that stays stable once it's set up - no walks, no grooming, no constant handling.
Some animals simply need less because of their biology. Cold-blooded invertebrates and reptiles have slower metabolisms, so they burn energy gradually and eat less often, and forest-floor species are adapted to stable, humid conditions that don't need constant tweaking. That's what makes the invertebrates below the lowest-maintenance pets you can keep.
The Best Low-Maintenance Pets: Invertebrates
Isopods - the standout choice
Isopods (woodlice, roly-polies, pill bugs) are arguably the best low-maintenance pet there is. Hardy, beginner-friendly species from the Porcellio, Porcellionides and Armadillidium groups live happily in a small ventilated tub with a moist substrate, leaf litter and a bit of bark. They need feeding only occasionally, are silent and odourless, and breed readily so a colony sustains itself for years with just a few minutes of attention a week. Most hardy species cope well with normal UK room temperature and need no special heating, which makes them well-suited to a British home. Individual isopods live one to three years, but a healthy colony effectively runs indefinitely. For which species to start with, see our guide to the best isopods for beginners, and for the full setup our UK beginner's guide to keeping isopods.
Springtails - the set-and-forget microfauna
Springtails (Collembola) are tiny, prolific and about as hands-off as a living thing gets. They live in the top layer of a moist substrate, feed on mould and decaying matter, and quietly keep an enclosure clean - which is why they're the standard cleanup crew in bioactive setups alongside isopods. A starter culture needs almost nothing beyond a humid tub and the occasional pinch of food, and it will happily tick along on its own. A brilliant first invertebrate, and one most keepers end up running permanently. Browse our springtails for sale if you'd like a culture to seed a setup.
Millipedes - low effort with a bit more presence
Millipedes offer the same simplicity as isopods with more visual interest thanks to their size. As detritivores they feed largely on their own substrate - deep, moist, nutritious material with leaf litter and rotting wood - plus the occasional soft vegetable once or twice a week. They're quiet, don't bite, and many species live five years or more, so they suit a keeper who wants a slightly longer-lived, more substantial invert. The one thing to get right is the substrate, since it's their main food source. Our millipedes for sale collection covers the beginner-friendly species.
Other Low-Maintenance Pets Worth Considering
If you'd prefer something outside the invertebrate world, a few other pets are relatively low-maintenance, though most need more space, kit or long-term commitment than the inverts above:
- Betta fish - colourful and calming in a heated, filtered tank of around 20 litres or more, with weekly partial water changes and daily feeding. They live three to five years and must be kept singly.
- African dwarf frogs - fully aquatic and entertaining to watch, kept in a filtered tank with hiding places. They need feeding several times a week and can live five to ten years.
- Leopard geckos - among the easiest reptiles, docile and silent, but a long commitment (10-20 years) needing a heated vivarium and a live-insect diet. Modest daily care once established.
- Corn snakes and ball pythons - fed only every week or two, but needing larger, carefully heated enclosures and a 15-30 year commitment, so best for those keen on snakes.
All of these are silent and space-efficient compared with a cat or dog, but none is as low-effort or as low-cost to run as a colony of isopods on a shelf.
Setting Up Your Invertebrates the Right Way
Whichever invert you choose, the care is much the same and simple: a ventilated plastic tub with a secure lid, a nutritious substrate, a calcium source for the isopods and millipedes, and a light feeding routine. The one thing worth getting right from the start is the substrate, because for isopods and millipedes it's a primary food source as well as a floor. Build it around a base of flake soil, crumbled white-rotted hardwood and organic topsoil, with leaf litter on top and sphagnum moss at the damp end. Avoid building the base around coco coir - it holds moisture well but is largely inert and feeds the colony almost nothing, whereas flake soil and hardwood do the same moisture job while actually providing food. Our complete substrate guide covers the layered recipe, and the components are ready to go in our accessories range.
Keep a normal room temperature (a heated UK home suits hardy species, and Powders and Dairy Cows breed faster with a small heat mat on a thermostat through winter), maintain a moisture gradient with one damp end, mist every few days, and feed lightly. A hardy starter species like Powder Orange is about the most forgiving first invertebrate you can keep.
Frequently Asked Questions
What is the most low-maintenance pet?
Invertebrates, and isopods in particular. They need only a small enclosure, feeding roughly once a week, and a few minutes of attention weekly. They're silent, odourless, breed on their own, and cost very little to keep once set up.
Are isopods good low-maintenance pets for the UK?
Yes - they're one of the best. Hardy species are happy at normal UK room temperature with no heating, live in a small tub, feed largely on their substrate, and a colony sustains itself for years. They're ideal for busy lives, small flats and first-time keepers.
Which pet can I leave for a week?
Isopods, springtails and millipedes typically cope with a week unattended if their enclosure is stable and lightly fed beforehand. Fish, amphibians and reptiles need an automatic feeder or a sitter, so the inverts win clearly here.
Do low-maintenance pets need a vet?
Most invertebrates rarely need veterinary care if their husbandry is right. Longer-lived reptiles like leopard geckos benefit from occasional health checks with an exotics vet, which is worth factoring in given their 10-20 year lifespan.
What is the best pet for a small flat?
Invertebrates, without question. A colony of isopods or a springtail culture lives on a shelf or desk, makes no noise, produces no smell, and needs no outdoor space - ideal for flats and shared housing.
Ready to Start?
If you want the joy of keeping a living creature without the time, cost and commitment of a cat or dog, invertebrates are the answer - and the very lowest-maintenance of all. Start with a hardy isopod species or a springtail culture, set up a simple enclosure with a good substrate, and let it settle.
