Your Gerbil Vet-Prep Sheet
Hayfold a warm home for small-pet folk · hayfold.com Gerbil — Vet-Prep Sheet
🔍 Find an exotic-mammal vet — before you need one
- Search the AEMV find-a-vet directory (the Association of Exotic Mammal Veterinarians), or, in the UK, the RCVS Find-a-Vet tool — or search “exotic / small-mammal vet near me”.
- Call ahead and ask the key question: “Do you see small / exotic mammals?” Not every vet does. Ask the exam fee while you’re on the phone, so the cost is one less panic in a crisis.
- Find and save one now, while things are calm — not in the middle of an emergency.
📇 Fill this in now — before the crisis
Two minutes now saves ten in a panic. Print it and keep it with your care notes.
🚨 Is this an emergency now?
See a vet promptly if you notice any of these:
- A seizure or a frozen, trance-like episode — gerbils are prone to epilepsy; usually brief, but tell your vet
- A red, crusty or sore nose or eyes (nasal dermatitis, often stress-related)
- Diarrhoea with a hunched posture, dull ruffled coat and low appetite — a sick gerbil needs a vet promptly
- Any lump, especially on the belly scent gland in an older gerbil
- Sudden fighting, wounds, or one gerbil driving another away (declanning)
- A degloved or injured tail after rough handling or a trapped limb
When in doubt, a vet call is never wrong — most issues are reversible if caught early.
🚗 On the way / while you wait
✅ Do
- Keep it warm — small mammals chill and dehydrate fast, and cold makes almost everything worse.
- Bring it in its own bedding/carrier with some familiar food.
- For rabbits and guinea pigs, keep offering their normal hay, greens and water — a gut that stops is an emergency.
- Bring a fresh dropping or urine sample if you can.
- Keep it calm and quiet.
⛔ Don’t
- Don’t give any human or OTC medicines — some common antibiotics are fatal to rabbits and guinea pigs.
- Don’t withhold food from a rabbit or guinea pig.
- Don’t let it get cold.
- Don’t handle it more than necessary.
🎒 What to bring
- A fresh dropping or urine sample, if you can collect one.
- Photos and a short video of the behaviour or symptom — it may not show it in the clinic.
- A note of your setup and exactly what — and how often — you feed.
- A note of eating, drinking and toileting over the last day.
- The animal in a secure, warm carrier.
🗣️ What to tell the vet
A general vet may not know this species. Come ready to explain its correct care:
- Enclosure
- A “gerbilarium” rather than a standard cage: large, with solid glass or plastic walls, a secure wire-mesh top, and a solid floor — deep enough to hold a thick bed of substrate. Barred cages aren’t recommended, because gerbils can injure their legs on the bars and gnaw them (damaging their teeth). Aim for around 50 cm of height with 20–30 cm of bedding, so they can dig proper burrows and still stand fully upright above ground. Include a stone or rough surface to help wear their claws down.
- Companionship
- Gerbils are clan animals (wild groups run from two to fifteen) and must never be kept alone. Keep them in same-sex pairs or groups formed early in life and kept stable — don’t add an adult stranger later (established clans rarely accept newcomers, except juveniles under about five weeks, introduced gradually through a split cage). Watch closely for sudden fighting between clan-mates (“declanning”); if it happens, they may need to be permanently separated. Never pick a gerbil up by its tail — the skin can slip off, exposing the bone.
- Temperature
- An ideal range is about 20–24°C. Keep them out of direct sun and away from damp and draughts; they’re desert animals but still need a stable, comfortable room temperature.
- Substrate
- A deep layer (20–30 cm) of a mix of rough-grained woodchips and hay, so they can dig and build stable burrows and gnaw at the same time. Give plenty of shreddable material too (ink-free cardboard, plain paper, toilet-roll tubes). Spot-clean every few days and deep-clean only every two to three weeks, since over-cleaning destroys their scent and burrows.
- Enrichment
- Gerbils are highly motivated to dig, gnaw and explore: deep substrate for tunnelling, plenty of cardboard and gnaw sticks to shred, and wooden tunnels, bridges and toys to climb on and chew. A large-diameter, solid, axle-free exercise wheel is good — never an open-rung wire wheel, which can trap and break a leg or tail.
- Diet
- A good-quality food made specifically for gerbils — a compound pellet or a proper seed mix — as the base. You can supplement with small amounts of fruit (pear, melon, apple, orange) and vegetables (cucumber, carrot, pumpkin, fennel) as part of the ration. Avoid feeding too many fatty seeds like sunflower (they cause obesity), and never give grapes or rhubarb, which are poisonous to rodents. Provide fresh water at all times.
- Supplements
- None needed on a good-quality gerbil diet.
⚕️ Small mammals are prey animals and hide illness until it is advanced, so any change in eating, droppings, drinking or behaviour is urgent — in rabbits and guinea pigs, not eating or passing no droppings for 12–24 hours can be a life-threatening emergency (gut stasis). They also chill and dehydrate quickly, so keep it warm. Tell the vet about your diet and any remedies you’ve used, and ask for exotic-mammal-safe medicines and doses — several antibiotics that are routine in other pets are dangerous to rabbits and guinea pigs.
Then note which of the warning signs (above) you are seeing, when they started, and whether they are getting worse.
❓ Questions to ask
- Do you routinely see small / exotic mammals? If not, can you refer me to a vet who does?
- What are the likely causes — and could my setup or diet be contributing?
- What is the treatment plan, the likely cost, and what should I watch for at home?
- How do I prevent this from happening again?
