Four Mongolian gerbils will need a cage that is at least 20 inches by 10 inches in size, with a height of at least 12 inches. This will provide enough space for them to move around, play, and burrow. It's important to provide enough space for each gerbil to have its own territory and to prevent territorial disputes. Additionally, providing plenty of toys, tunnels, and hiding spots will help keep the gerbils entertained and happy. **

No, gerbils do not hibernate. They are active animals that remain active throughout the year. In the wild, gerbils live in burrows in the desert and are adapted to survive in harsh conditions without needing to hibernate. In captivity, gerbils also do not hibernate and should be kept in a warm and comfortable environment to ensure their well-being. **

Yes, gerbils can eat almonds in moderation as an occasional treat. Almonds are a good source of healthy fats, protein, and fiber, but they are also high in fat content, so they should not be a regular part of a gerbil's diet. It is important to remember that almonds should be given in small amounts and only as an occasional snack to prevent any digestive issues. **

Gerbils can eat a variety of fruits and vegetables in moderation as part of a balanced diet. However, it is important to avoid feeding them foods that are high in sugar or fat, as well as any toxic foods. It is always best to research specific foods before feeding them to your gerbil to ensure they are safe and healthy for them to consume. **

While it is difficult to determine whether desert gerbils mourn in the same way that humans do, there is evidence to suggest that they may experience some form of grief. Studies have shown that gerbils can exhibit behaviors such as decreased activity and reduced appetite after the loss of a companion. Additionally, they may show signs of distress and vocalize more frequently. While it may not be the same as human mourning, these behaviors indicate that gerbils may experience some form of emotional response to the loss of a companion. **

Gerbils are very clean animals and they bathe themselves by rolling in sand. They have special oil glands in their skin that produce an oil which helps to keep their fur clean and healthy. Rolling in sand helps to remove excess oil and dirt from their fur, and also helps to prevent their fur from becoming matted. It's important for gerbils to have access to a sand bath in their habitat to maintain their hygiene. **

Yes, gerbils can eat millet as part of their diet. Millet is a nutritious and safe option for gerbils, providing them with essential nutrients such as protein, fiber, and various vitamins and minerals. However, millet should be given to gerbils in moderation as part of a balanced diet that includes a variety of other seeds, grains, and fresh vegetables. It's important to ensure that the millet is clean and free from any pesticides or contaminants before offering it to your gerbil. **

Gerbils are social animals and generally prefer to live in pairs or groups. They can become lonely and stressed if kept alone for long periods of time. It is recommended to keep gerbils in pairs or small groups to provide them with social interaction and companionship. However, if a gerbil is kept alone, it is important to provide plenty of enrichment and interaction with their human caretaker to prevent loneliness and boredom. **
