All animals that can reproduce sexually possess a kundalini. As kundalini spirit relates to thinking prowess, the capability to activate kundalini does not exist in animals. In very rare cases some animals could exercise partial awakening of kundalini by indulging in very noble deeds.
Jainism believes before manifesting form of Mahavira, the soul atman of Mahavira manifested form of a lion. The advent of Mahavira was directly from stage of an animal, the king of jungle lion. Personally I do not believe so. It just could not happen. Awakening of kundalini takes time.
Even in human form God Almighty ordained a long journey of 1.1 million manifestations before our kundalini activated fully. Then how come the soul atman of Mahavira could take a quantum jump from level of an animal lion to state of Mahavira, an enlightened one.
As a human being we all have passed through 7.3 million manifestations in insect, plant and animal form. Upanishads (independent spiritual treatises) were absolutely clear on this evolutionary timeline.
Born an animal one can definitely make a faster progress on kundalini scale provided the animal could think spiritually. But how could an animal think spiritually?
Spirituality relates to working for welfare of others. When animals worked for welfare of other beings, it automatically results in partial activation of kundalini. Even in animal form this was definitely possible. There are instances in history when animals saved other forms of life even at the risk of their own life. Such animals get awarded by partial activation of kundalini.
Some animals pet or wild were definitely nobler than others. Such animals could definitely precipitate their kundalini shakti unknowingly. As activation of kundalini was very slow even in human beings, mankind would hardly witness partial awakening of kundalini in animals.
