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 only light feeding a few times a week, are silent and low in odour when kept clean, 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 the place to start - and they're exactly what we keep and sell here at PostPods.
What "Low-Maintenance" Actually Means
One caveat up front: low-maintenance doesn't mean no-maintenance. Every pet needs a good 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 why the invertebrates below ask so little of your time.
The Best Low-Maintenance Pets: Invertebrates
Here is how four of the invertebrates we keep and sell compare on the time and effort they ask of you, from our own care guides:
| Pet | Feeding | Weekly time | Heat in a UK home | Lifespan |
|---|---|---|---|---|
| Isopods | Leaf litter, rotting wood and a calcium source always in; a little fresh food twice a week, with protein once or twice a week | A few minutes: a mist every few days and light feeding | Hardy species need no heat mat in a heated home; Powders and Dairy Cows tolerate a heated room but breed faster with a small mat on the side of the tub, on a thermostat, through the colder months | Mostly one to three years each; a healthy colony keeps going for years |
| Springtails | A pinch of yeast or a few grains of rice every few days in a culture tub; in a shared enclosure they mostly graze the soft mould and fine debris already there | Almost none beyond feeding and a regular check that the culture is damp | Temperate whites need no heat mat, as a heated home sits inside their 15 to 22°C for most of the year, but keep them out of summer heat; Thai Reds want 24 to 28°C, so a heat mat on the side of the tub, on a thermostat | Several months each; a well-kept culture keeps going for years |
| Millipedes | Mostly their own bed of leaves and rotting wood, topped up as it is eaten; cuttlebone always in; a little fresh food two or three times a week, never daily, and protein once or twice a week | A few minutes, mostly topping up leaves and wood | Tropical species want around 22 to 26°C, so a heat mat on the side wall, on a thermostat, through the colder months; the Ivory needs none | Around five years for mid-size species, seven to ten for the African giants |
| Madagascar hissing cockroaches | Fruit and vegetables a couple of times a week, with a little protein; leftovers out after a day or two | A couple of feeds, lifting leftovers, and regular clearing of droppings and shed skins | A heat mat on the side of the tub, on a thermostat, through the colder months; in summer a typical home keeps them going, though they are slower and breed less | Two to five years |
Isopods - the standout choice
Isopods (woodlice, roly-polies, pill bugs) make a very low-maintenance pet. 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 only a little fresh food twice a week, are silent and low in odour when kept clean, and breed readily so a colony sustains itself for years with just a few minutes of attention a week. Hardy species need no heat mat in a heated home, which in England averages about 19°C over the heating season, though Powders and Dairy Cows breed faster with a small mat on the side of the tub, on a thermostat, through the colder months. 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 very hands-off. They live in the top layer of a moist substrate and feed on soft mould and decaying matter, 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 a little soft vegetable two or three times 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. Get the substrate right, 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 at least 20 litres, with weekly partial water changes and daily feeding. They live around two to five years. Keep a male alone or with very placid tank mates, and never with another male, as males fight.
- 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 substrate is worth getting right from the start, 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 the side of the tub, 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 a forgiving first invertebrate.
Frequently Asked Questions
What is the most low-maintenance pet?
Invertebrates, and isopods in particular. They need only a small enclosure, a little fresh food twice a week, and a few minutes of attention weekly. They're silent, low in odour when kept clean, breed on their own, and cost very little to keep once set up.
Are isopods good low-maintenance pets for the UK?
Yes. Hardy species need no heat mat in a heated home, 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 suit a small flat well. A colony of isopods or a springtail culture lives on a shelf or desk, makes no noise, has little smell when kept clean, and needs no outdoor space - ideal for flats and shared housing. Our guide to small pets for flats and small spaces goes through how much room each pet needs.
