Let them see the body before you say goodbye

A guinea pig that's allowed to sniff over its dead cagemate tends to stop searching and calling out for them within a day or two, instead of pacing the hutch for weeks. Guinea pigs run almost entirely on scent and constant vocal contact with a herd mate, so when one vanishes with no explanation the survivor just keeps checking — the hay corner, the food bowl, wherever they last saw them — because as far as it knows, nothing's actually changed except the other pig's gone quiet. Most rescues who handle a lot of bonded-pair deaths will tell you the same thing, even though nobody's run a formal study on it. When Digger died overnight I nearly tidied him away before Wilbur woke up, out of some instinct to protect him from it — a rescue I used to foster through talked me out of that habit years ago, and I've never regretted it since.

Try it
If your guinea pig died at home, leave the body somewhere the survivor can approach in their own time for ten to fifteen minutes before you remove it — don't force a nose-to-nose introduction, just let them come to it.
Watch rather than intervene: some pigs sniff once and wander off, others circle and nudge for a while, both are normal.
If your guinea pig died at the vet's, ask if you can bring the body home briefly for this — most small-animal vets understand exactly why and will accommodate it.

Be the herd yourself, little and often

Extra time near you won't replace a guinea pig companion, but it fills the same low-level need for constant company that a herd animal runs on, and it buys you real time to arrange a proper introduction. Guinea pigs bond through near-constant background presence — the chattering, popcorning and low rumbling that goes on between cagemates all day — not scheduled cuddle sessions, so what actually helps is being in the room more often, not one or two dedicated ten-minute play sessions. This is a stopgap, not a fix.

Try it
Move the hutch, or a floor pen, somewhere you actually spend time — living room corner, next to your desk — for the transition period.
Talk to them while you're doing something else nearby; guinea pigs learn a familiar voice as a safety cue even without direct handling.
Sit at floor level with a bit of veg for a few minutes each visit, but don't force lap time if they're not into it — a wary pig doesn't need one more new stressor.

Give her more floor space, not a smaller cage

A guinea pig who's lost their built-in lookout partner is now doing all the herd's vigilance alone, so a bigger, busier setup with more places to disappear helps more now than it did when there were two of them. In a pair, guinea pigs take turns relaxing while the other half-listens for trouble; solo, every rustle and door-slam is suddenly their problem to notice, and what looks like restlessness in a newly-alone pig is often just a nervous system running with no backup. The classic mistake is downsizing because 'it's only one now' — I've seen keepers move a grieving survivor into the smaller single-pig hutch a well-meaning pet shop assistant recommended, at exactly the moment they need more room, not less.

Try it
Don't shrink the enclosure — if anything, add a second hide and a snug tunnel so there's always somewhere to vanish to.
Throw in a cardboard box maze or a few extra hidey-holes for the first few weeks — cheap, disposable, gives them options.
Keep the layout otherwise familiar — don't move the food bowl or hay corner at the same time, that's one more thing to relearn.

Find a rescue that runs proper bonding introductions

A new companion chosen and introduced by a rescue running dedicated bonding sessions settles in far more reliably than one bought same-day and dropped straight into the cage, because guinea pigs are territorial and a lot rides on matching temperament and using neutral ground. Good rescues bring several pigs together on turf that belongs to none of them, watch for the normal sorting-out behaviour — some rumbling, chasing and mounting is just pigs working out a hierarchy, not a red flag — and steer you toward the right sex pairing too, which is where a lot of same-day matches go wrong. Even a good rescue match still needs a slow, supervised introduction at home with escape routes available; a solid pairing on paper isn't the same as an instant friendship.

RSPCA — guinea pig companionship

Try it
Search for a guinea pig rescue near you offering bonding or 'speed dating' sessions — plenty run these specifically for bereaved solo pigs, sometimes free.
Bring her along to meet a few candidates on the rescue's neutral territory, not straight into your existing set-up at home.
Once you've got a match, still run a slow, supervised introduction on neutral ground at home, with hides and escape routes available, rather than assuming the rescue's pairing means an instant friendship.

Watch appetite and droppings like it's already an emergency

A guinea pig who stops eating or stops passing droppings after losing a cagemate needs an exotics-experienced vet within hours, not a few sympathetic days to grieve, because grief and gut stasis look identical from outside the cage. A guinea pig's gut has to keep moving almost constantly, and a lot of pigs eat side-by-side and slow right down when their mate's not there to eat alongside them — so the exact stress of bereavement is also exactly the trigger that can tip a gut into stopping. This isn't a moment for troubleshooting at home: not eating, or not producing droppings, for 12 hours is a genuine emergency, and a hunched, unusually still or unresponsive guinea pig needs a vet visit, not a checklist.

PDSA — guinea pig health and gut stasis

Try it
Weigh her daily on kitchen scales for the first couple of weeks — weight loss often shows up before you'd notice anything by eye.
Check food intake, water level and the droppings in the hutch at set points through the day, not just a glance in passing.
If it's been 12 hours without eating or without droppings, or she's hunched, still and unresponsive, treat it as a same-day emergency and get to an exotics-experienced vet — this is a vet visit, not a checklist.

What didn't make the list

Pairing her with a rabbit "for company"

Still floated in pet shops as an easy fix, but rabbits and guinea pigs shouldn't share a hutch — a rabbit's kick can seriously injure a guinea pig, their diets differ (guinea pigs need dietary vitamin C, rabbits don't), and rabbits can carry bacteria guinea pigs are vulnerable to. It solves the paperwork problem of "has a companion" without solving the actual one.

Mirror or plush "guinea pig buddy" toys

Marketed as an instant fix for a lonely guinea pig, but she doesn't read a reflection or a stuffed toy as another guinea pig — no scent, no warmth, no grooming, no wheeking back. Harmless as cage furniture, but treating one as a substitute just delays finding her a real companion.

Questions people ask

Is it cruel to let my guinea pig see her dead cagemate?

No — if anything, it's the opposite of most people's instinct. Rescues that deal with bonded-pair deaths often recommend it precisely because a short, calm, supervised look and sniff tends to shorten the searching and calling-out phase rather than prolong any distress. If she seems to want to keep her distance, don't force her closer.

How quickly do I actually need to find her a new companion?

There's no fixed safe number of days, but start the search straight away — guinea pigs are herd animals, and solo housing isn't recommended even short-term (it's against welfare guidance, and outright illegal in a few countries, including Switzerland). Lean on extra human interaction and a busier room to bridge the gap; a decent bonding-focused rescue can often match her within a couple of weeks.

She's gone quiet and isn't eating her usual amount since her friend died — is that just grief?

You can't reliably tell grief-related appetite loss apart from gut stasis just by watching from outside the cage, so treat any real drop in eating or droppings as urgent rather than something to monitor for a few more days. Not eating, or not passing droppings, for 12 hours is a genuine emergency in guinea pigs — this is a same-day vet visit, not a wait-and-see situation.
