This is Stanley. He is a domestic rabbit. He is a boy. Animal shelter staff estimates he is between two and three years old.
He was likely someone's holiday gift who was let go after the family tired of him. Rabbits' teeth grow their whole life, so it is important having the right diet for them, which should be a good quality hay and some pellets, (of course, carrots and lettuce are also good) access to water and just some love and attention. Certainly he should be in a cage, but he can come out and play and let him explore and hop around.
There are vets that will spay and neuter rabbits. Not all vets do it, but they're more considered your exotic pet. He has not been neutered yet. We don't want it to be an impulse adoption, so filling out an application, making sure the whole family is in agreement on adopting a rabbit will be a requirement, and usually it takes a day or two.
