1. Increased activity: During the estrous phase, female hamsters may exhibit increased activity levels. They might become more restless, move around more frequently, and display a higher level of curiosity and exploration.
2. Changes in behavior: Female hamsters in heat may show changes in their behavior. They can become more affectionate and seek attention from their owner or cagemates. Some females may also become more playful or exhibit a higher interest in interaction.
3. Scent marking: Female hamsters in heat often engage in scent marking. They might rub their flanks against objects, walls, or other surfaces to leave scent marks. This behavior serves to attract potential mates.
4. Lordosis posture: When a female hamster is receptive to mating, she will adopt a lordosis posture. In this position, the female's back will be arched, her head will be lowered, and her rump will be raised. This posture signals her readiness to mate.
5. Vulva changes: The vulva of a female hamster in heat may appear slightly swollen or enlarged. This is a physical sign that indicates her reproductive system is preparing for mating.
6. Mucus discharge: During estrus, female hamsters may produce a small amount of clear or white mucus discharge from their vagina. This discharge can be a sign that she is in heat and ready to mate.
7. Changes in vocalization: Some female hamsters may emit specific vocalizations, such as chirping or clicking sounds, during the estrous phase. These sounds can be used to attract potential mates.
It's important to note that not all female hamsters display all of these signs when in heat. Some may exhibit only a few of these behaviors, while others may show more pronounced changes. If you suspect your female hamster is in heat, it's a good idea to consult with a veterinarian to ensure her well-being and proper care during this period.
