I can't speak for Buddhism but you got Hinduism wrong. Hinduism explicitly allows all Jivas to attain Moksha. There is an entire song on this called "Gajendra Moksha" where Gajendra (the Elephant) is caught by Makara (crocodile) and is rescued by Lord Vishnu, who grants Gajendra Moksha from Samsara. Another example would be that of Jatayu where Lord Rama gives him the status of his father (King Dasharatha) and performs his final rites, and then granting him Moksha. There are innumerable tales of animals getting Moksha in Hindu scriptures. Just provided 2 such instances.
