Questionis it ever too late to get the rabbits neutered?
AnswerEach vet might give a different answer depending on their experience neutering different ages of rabbits. Generally if the rabbit is healthy and less than 6 years old, a neuter will probably be fine.
If the rabbit is older, a vet may do some bloodwork to see if the rabbit is healthy enough. And may provide council on the neuter of an older rabbit.
I hope this helps
