Tail injuries from improper handling can cause the tail skin to die and slough off - early sign is fur loss from the tip of the tail.

Epilepsy is very common - between 20-50% of pet gerbils have seizures, often triggered by fright, handling, or a new environment.

Tumors (benign and malignant) are fairly common, especially in females over two years old, often affecting ovaries or skin around ears, feet, and tail base.

Misaligned incisors can overgrow and injure the mouth - watch for dropped appetite, drooling, weight loss, or foul breath.

Tyzzer's disease is the most common infectious disease in gerbils; signs include ruffled fur, lethargy, hunched posture, poor appetite, and diarrhoea.

Gerbils are susceptible to diet-induced diabetes, similar to other desert rodents, so diet should be monitored carefully.

Inner ear problems can cause a gerbil to lean noticeably to one side and may be linked to ear infections.

Gerbils with 'extreme white spotting' colouring are prone to deafness, thought to be due to lack of pigmentation in and around the ear.

Gerbils are social animals that enjoy the company of humans and other gerbils, making them generally easy and pleasant to handle.

They are typically not aggressive and rarely bite unless stressed or provoked - calm, gentle handling reduces this risk.

Gerbils are described as gentle and hardy, so they tolerate handling well but should never be rushed or startled.

They rely heavily on scent to identify familiar individuals - unfamiliar smells can trigger aggression toward other gerbils nearby.

Groups have a dominant gerbil that may bully others, so watch for tension or bullying behaviour when gerbils are housed together.

Avoid blowing in a gerbil's face, as this can trigger a seizure - keep interactions calm and non-threatening.

They are very clean animals with little odour, so grooming sessions should be low-stress rather than intensive.

A new environment can cause stress and potentially trigger seizures, so introduce the gerbil to new spaces slowly and quietly.

They rely heavily on scent to identify familiar individuals, so washing hands before handling can help avoid triggering defensive reactions.

Gerbils are known to attack animals or gerbils carrying an unfamiliar scent, so introductions to other pets should be approached with caution.

They are small and active animals, so a secure, calm grip is important to prevent them falling or escaping during handling.

Gerbils produce very little odour due to efficient kidneys, so they are clean animals and do not require frequent bathing or grooming.

Avoid blowing in a gerbil's face, as this is known to cause significant stress and can trigger a seizure response.

Like many small rodents, gerbils may carry lymphocytic choriomeningitis virus (LCMV) - pregnant women and immunocompromised people should take extra care or avoid close contact.

Gerbils can harbor mites or other parasites - keep their enclosure clean and have a vet check any pet showing signs of skin irritation to reduce any risk of spread.

Germs can spread via gerbil droppings, urine, or saliva - avoid touching your face when handling gerbils and clean their cage regularly wearing gloves.

Children, elderly people, and those with weakened immune systems are more vulnerable to pet-related germs - supervise handwashing after any contact with gerbils or their bedding.

Bites or scratches from gerbils can introduce bacteria - clean any wound promptly with soap and water and monitor for signs of infection.

Always supervise young children handling gerbils and help them wash hands right after - kids are more likely to touch their faces and are at higher risk from germs.

When an older female gerbil loses her mate, she almost always gives up on reproducing entirely - even if potential partners are available.

Their hearing range spans from low-frequency foot drumming to high-frequency chirps, making them a potentially better model for human hearing research than mice or rats.

Up to 20% of wild gerbils spontaneously develop epileptic seizures, often triggered by something as routine as cage cleaning.

Gerbils use scent to tell clan members apart - and will attack or even kill any gerbil carrying an unfamiliar smell.

Gerbils have evolved kidneys so efficient at conserving water that they produce barely any waste, making them surprisingly odour-free pets.

Gerbils with 'extreme white spotting' colouring are prone to deafness, likely because of reduced pigmentation in and around the ear.
