The reasons why female cats walk with their backs arched:
1. When cats approach prey quietly, they will arch their backs and be ready to attack at any time so that they can jump on the prey.
2. When a cat is frightened, it may also walk with its back hunched over, its tail erect, and its hair erected.
3. If the cat is infected with parasites, causing local itching and walking with a hunched back, the cat needs to be dewormed in time.
4. When a cat is feeling unwell, has abdominal pain, or spinal pain and will arch its back, you need to take the cat to the pet hospital for examination and treatment in time.
5. If the cat walks with its back hunched over for a long time, it is likely to be caused by calcium deficiency. The cat needs to be taken for examination. If it is calcium deficient, calcium tablets need to be fed to improve the situation.
