i’m concerned that your husband is wanting to “get rid” of him. rabbits are not a cheap, low-maintenance pet. they require vet care and a specialized diet of fresh veggies and hay every day. i’m not sure how much thought was put into your decision to get a rabbit, but i’m very happy you’ve found this site. we can answer questions for you and help in many different area of rabbit care.
first off, rabbits really shouldn’t have an odor to them if you’re cleaning the litterbox and cage frequently enough. what kind of litter do you use and how often are you cleaning the cage?
you may want to try putting a layer of hay in the litterbox. rabbits like to munch while they potty, weird as it may sound. just be sure to replace the hay everyday as it may get soiled.
if he pees in another spot, make sure to clean it up as soon as possible and try putting the wet paper towel in the litterbox so he can associate the smell.
check out the bunny info > litterbox training section at the top of this page. that gives more tips and suggestions.
the most important thing will be getting him neutered. at his age, he might be old enough. you may want to start looking for a rabbit vet now. puberty sets in at about 4-7 months depending on the rabbit, and he will most likely become very territorial and aggressive at that time. you will notice an increase as well in him marking with urine. neutering will help with those behavioral issues, litter habits in most cases, and increase the likelihood that he will live a longer, healthier life.
