Yes, your gerbil can get stressed when encountering an unfamiliar or uncomfortable situation. Here are some situations your gerbil might find stressful.

Inadequate housing: Your gerbil's home is a sanctuary. Make sure there is plenty of room to eat, sleep and exercise. A gerbil cage, either a glass, plastic or metal cage with a solid bottom or a 15-gallon aquarium, should provide adequate room for two gerbils. Ensure the cage is escape-proof. It is best to provide the largest habitat possible. Make sure to include bedding.

Food: Be certain that food is always available for your gerbil. Pre-packaged gerbil pellets and seed mixtures are readily available and easy to feed. Small amounts of fresh fruits and vegetables can be given daily but discard after 24 hours. If changing your gerbil's diet, do so gradually.

Water: Even though your gerbil originally comes from a desert environment and can go for long periods of time without water, a water drip bottle filled with fresh water should always be accessible. Your gerbil's water should be changed daily so it is always fresh.

Lack of Companionship: Gerbils need the companionship of another gerbil.

Change in Handling or Picking Up Your Gerbil: Establishing a routine and handling your gerbil gently are important points to keep in mind.

Lack of Activity/Exercise/Toys: Your energetic pet will play day and night. Help maintain your pet's health by providing toys to entertain and utilize energy.

Temperatures not Conducive to Your Gerbil's Comfort: Gerbils acclimate well to average household temperatures but be cautious of extreme temperature changes and keep their habitat out of direct sunlight and away from drafty areas.

Illness: Gerbils are generally very healthy animals but like any pet, they can become ill when stressed or exposed to pathogens.
