do female rabbits smell more than male ones?

Rabbits do not go have heat cycles. Conception is always possible because they are reflex ovulators. In other words, they are always receptive and ready to get pregnant.

i've had both males and females that i kept indoors. Personally, i found that the females' pee and poop stunk way more. i preferred the males personality better too. My boy bunnies were always very affectionate and would give me kisses. :)

Both male and female rabbits can be very territorial. Males will grunt, lunge and bite and will pee and poop everywhere - my bed was a particular favorite - to mark their territory. Females can also become aggressive - grunting, lunging and biting and will exhibit nesting behaviour where they dig at the floor of their cage for hours and hours, especially at night.

Ideally, you will have your new bunny spayed or nuetered to curb aggressive behaviour due to hormones and it's usually due to hormones.

Actually the bucks tend to mark their territory and you might not like how they go about that. ;) Bucks can be more personable than a lone female though. I had a little buck as my first, he was a sweetheart. Just be aware they will pee everywhere on everything when they're still young.
