The reasons why a cat keeps meowing while walking with its body lowered:

1. If a cat keeps meowing while walking with its body lowered, it may be in estrus and needs to be bred or sterilized as soon as possible.

2. It may be that there was a fight with other cats during play, which caused damage to the muscles of the hind legs. Therefore, the cat will walk with his body lowered and needs to be treated in a pet hospital in time.

3. If there is no sense of security around the cat, the cat will be very scared. In order to observe the surrounding environment and protect itself, the cat lowers its body and walks. The owner can gently stroke the cat to make it feel safe.
