House Sitting With Rabbits, Guinea Pigs, Rats, and Mice

Home > Blog > House Sitting With Small Pets

Cats and dogs dominate house sitting listings, but a real slice, somewhere around 3-5% by our own rough count, involve rabbits, guinea pigs, rats, or mice. We've never house sat for someone else's small pet through a platform, but we've owned rabbits, rats, and mice ourselves, and there's real, practical knowledge worth passing on before you accept one of these sits.

The Rabbit: More Personality Than You'd Expect

I had a rabbit with my sisters when I was around ten, sold to us as a miniature breed. It grew to roughly 60cm, clearly not miniature at all, which is worth remembering if you're ever told a rabbit's adult size with confidence, breeders and sellers get it wrong more often than you'd think.

Rabbits have genuine personality. Ours loved being cuddled, properly loved it, and had an enormous amount of energy, sprinting across rooms at real speed. One thing that catches first-timers off guard: rabbits thump the ground loudly, hard enough to actually hear from another room, usually as a warning or reaction to something. It's a completely normal behaviour, not a sign of distress on its own.

The practical downside is toileting accuracy. Rabbits don't always use their cage or litter tray consistently, and you'll likely find droppings, sometimes more, in places around the house you weren't expecting. If a sit involves a rabbit with any real roaming freedom, budget real time for cleanup, not just feeding, the same kind of honest expectation-setting we cover in our what house sitters can and cannot change guide.

What to Actually Watch For With a Rabbit

Rabbits are prey animals, which means they instinctively hide illness until it's genuin​ely serious. This matters enormously for a sitter, since a rabbit that seems fine on the surface can deteriorate quickly, and subtle changes are often the only warning you'll get.

The single most important habit here: always keep fresh grass hay available, it should make up roughly 75-80% of a rabbit's diet, and avoid sugary treats or bread entirely, their digestive systems genuinely can't handle it well. Daily space to hop and move matters just as much as diet, a rabbit confined to a small cage all day is a welfare issue, not just a preference. If anything here looks genuinely off, this is exactly the kind of situation our pet emergency guide covers, contacting a vet quickly matters more with rabbits than almost any other small pet, given how fast they can decline.

Rats: Intelligent, Occasionally Painful, and Capable of Something Darker

I had a rat briefly as a kid, around eight years old, and it didn't last long. It hid constantly, to the point where mess would build up in spots I genuinely couldn't reach, and the smell became a real problem in the house. It also bit, hard enough to genuinely hurt, which is a harder thing to manage with young kids involved.

Years later in Australia, I kept up to ten rats at once in a large cage. Rats are genuinely intelligent, trainable, sociable animals, and keeping several together is common and usually fine. But it's worth knowing honestly: under stress or competition within a group, rats will sometimes cannibalise each other, a genuinely different risk profile to the biting concerns covered in our dog bite during a house sit guide, but worth the same level of upfront honesty with a homeowner.

I found partially eaten rats in the cage more than once. This isn't meant to be alarming for its own sake, it's a real, documented behaviour in rodent groups under the wrong conditions, and if you're sitting for a group of rats, it's worth asking the homeowner directly about the group's history and dynamics rather than assuming everything's fine because they're currently living together.

Mice: Small, Fast, and Genuinely Hard to Find Once Loose

We also kept mice as kids, and the one thing that stands out clearly: they escape, and once they're loose in a house, finding them again is genuinely difficult. They fit into gaps you wouldn't think possible and go quiet the moment they sense they're being searched for. If you're sitting for mice, treat enclosure security seriously, checking latches, gaps, anything that could let them out, since prevention is far easier than recovery.

What to Actually Watch For With Guinea Pigs, Rats, and Mice

These animals share some genuine, non-obvious risks worth knowing before you accept a sit involving them, particularly guinea pigs, which are more medically sensitive than most people expect.

One detail worth knowing specifically: guinea pigs cannot produce their own vitamin C and need it supplemented directly, usually through a chewable tablet rather than added to water, since it breaks down quickly once dissolved. If a homeowner has guinea pigs, ask directly whether they're already on a supplement and how it's given, exactly the kind of detail worth raising on the pre-sit video call rather than discovering after you've already arrived.

What All of These Animals Actually Have in Common

A few things apply across rabbits, guinea pigs, rats, and mice as a group, and they're the genuinely useful takeaways if you're considering a sit like this.

They all like to hide in tight, dark spaces. If one gets loose in the house, that's where to look first, under furniture, behind appliances, inside anything with a gap.

Food, fresh water, and a reasonably sized enclosure with mental stimulation covers the basics for all of them. None of these animals need walks, which genuinely makes them easier to manage day to day than a dog, letting them out to run in the house, if the homeowner allows it, is usually enough exercise on its own.

The real ongoing task is bedding, not feeding. Straw or bedding needs changing regularly, and if it isn't, the smell builds up fast and spreads through the house. This is the part that actually takes effort on a sit like this, not the animal itself.

Biting is a real possibility, particularly with rats, and it can genuinely hurt. It's worth asking the homeowner directly whether the specific animal has a history of nipping, and being sensible around handling if you're unfamiliar with that individual pet's temperament.

Are These Sits Actually Worth Considering?

Genuinely, yes, and they're underrated. Cat and dog listings dominate the market, which means small pet sits often see less competition. If you're comfortable with the honest reality of hiding, occasional bites, and the bedding smell, these can be some of the easiest sits available, no walks, no complex medical routines in most cases, just consistent, low-effort daily care.

Conclusion

Rabbits, guinea pigs, rats, and mice are a genuinely overlooked category of house sit, the same underrated value we talk about across our beginner's guide to landing your first sit. They're not high-maintenance, they don't need walking, and the actual challenges, hiding, occasional bites, bedding smell, are manageable once you know what to expect going in. We've never done one of these sits through a platform ourselves, but years of owning these animals directly gave us a real, honest picture of what a sitter should actually watch for.

Caro and I have completed 20 house sits across 12 countries, driven 19,000km across Europe in our 1998 VW T4, and saved over $26,500 in accommodation costs over three years of house sitting. If you've sat for a rabbit, rat, or guinea pig yourself, we'd love to hear how it went, DM us @housesittersguide, we answer everyone.

Frequently Asked Questions

• Are rabbits rodents?

  No, rabbits are lagomorphs, a separate biological group from rodents like rats, mice, and guinea pigs. It doesn't change day-to-day care much, but it's a common misconception worth knowing.

• Is house sitting for small pets like rabbits or guinea pigs easier than a dog?

  Generally yes. None of these animals need walks, and food, water, and a properly sized enclosure with some mental stimulation cover the basics. The real ongoing task is regular bedding changes to control odour, not exercise or complex routines.

• Do rats actually hurt each other if kept in groups?

  It's a real, if less commonly discussed, risk. Rats kept together can sometimes cannibalise each other under stress or competition. If sitting for a group of rats, it's worth asking the homeowner about the group's history and dynamics beforehand.

• What should I do if a small pet escapes its enclosure during a sit?

  Check tight, dark spaces first, under furniture, behind appliances, anywhere with a gap. These animals are naturally inclined to hide, and mice in particular can be genuinely difficult to locate once loose, so prevention through secure enclosures matters more than recovery.

• How common are rabbit, guinea pig, or rat house sits compared to cats and dogs?

  Less common, but real. Roughly 3-5% of listings we've come across involve small pets like these, and since most sitters focus on cats and dogs, competition for these listings tends to be lower.
