1. Behavioral Changes:
- Increased restlessness and activity
- Mounting behavior: Does may mount other rabbits, humans, or objects.
- Circling: The doe may run in circles or have a "figure-8" pattern of movement.
- Nesting behavior: Does may start building a nest by gathering hay or other materials.
- Increased grooming: They may excessively groom themselves and their partners.
- Vocalization: Some does may make unique vocalizations during heat.
2. Physical Changes:
- Swollen and reddish vulva: The external genitalia may appear enlarged and pink or red.
- Mucous discharge: Clear or slightly brownish vaginal discharge may be noticeable.
- Increased urination: Does may urinate more frequently and mark their territory with urine.
3. Receptivity to Males:
- When a doe is in heat, she becomes receptive to breeding with a male rabbit (buck). She allows the buck to mount her and will typically raise her hindquarters and hold her ears back during mating.
The heat cycle in rabbits is relatively short, usually lasting 10-15 days. However, it can vary among breeds and individual rabbits. If breeding is not desired, it's crucial to separate male and female rabbits during this period to prevent unplanned pregnancies. Additionally, spaying female rabbits is a common practice to avoid the heat cycle and various reproductive-related health issues.
