Its a toss up with the males. Some spray, some don't. I had a pet male in the house for a year and he never sprayed. And i;ve had others who started making a big mess at about 3 months. A lot depends on personality. I don't expect Zippity to spray (although anything is possible).
I actually find the does to be worse.....they are hormonal and can be messy. however, Zippity's mom was very well litterbox trained and not messy. Not all does are that way.
I prefer bucks as pets. Less hormonal and cranky.....and if they do start being too "boyish" neutering is not expensive. Spaying a female is EXPENSIVE....and can be hard to find a vet to do it. My regular vet will do male rabbit neuters at cat neuter pricing ($40).
