How about a custom portrait of him with a rabbit or a bunny? You can hire an artist to create a digital illustration or painting of him holding or interacting with a rabbit. Alternatively, you could get him a rabbit-themed gift, such as a cute bunny plushie, rabbit socks, or a rabbit-printed t-shirt. Additionally, you might consider taking him to a local animal sanctuary that specializes in rabbits or volunteering at one together.
Or you can get him a star map with the date when he was born.
