What does it mean if the gerbil gets fat suddenly?

1. Overeating: Gerbils are prone to overeating if they have unlimited access to food. A sudden increase in food intake can lead to rapid weight gain.

2. Lack of Exercise: Gerbils need regular exercise to stay healthy and maintain a healthy weight. If your gerbil is not getting enough exercise, it may become overweight.

3. Genetics: Some gerbils are more prone to obesity than others due to their genetics.

4. Age: As gerbils age, their metabolism slows down, making them more likely to gain weight.

5. Health Problems: Certain health conditions, such as hypothyroidism, can cause weight gain in gerbils.

6. Stress: Stress can lead to overeating and weight gain in gerbils.

If you notice that your gerbil is getting fat suddenly, it's important to take action to prevent serious health problems. Start by reducing the amount of food you're giving your gerbil and increasing the amount of exercise it gets. You should also take your gerbil to the vet to rule out any underlying health problems.
