A buck who backs up to furniture, flicks his hind legs, and leaves a sharp-smelling arc of urine is not being dirty or spiteful; he is advertising. Spraying is mostly hormonal scent-marking, aimed at territory, at other animals, and sometimes proudly at you, and it follows a hormonal logic that cleaning alone never defeats. Treat the cause first, protect the home second, and expect the habit to fade rather than stop overnight.
Talk to Your Vet About Neutering
The most effective step is neutering, discussed with the vet as a conversation rather than a booking made in frustration. Framed honestly, neutering settles spraying for many bucks once hormone levels fall, and the vet can explain the health and behavior benefits that come with it, along with timing, aftercare, and what change to expect and when. Ask how long spraying may continue during the settling weeks, because marking that lingers briefly after surgery is common and discourages owners who expected an instant switch.
A vet conversation also separates marking from medical trouble. Spraying that arrives suddenly in an older, already neutered rabbit, especially alongside straining, dribbling, blood in the urine, or appetite change, is a health question for the vet to investigate, not a behavior problem to manage at home. Describe where, when, and how often he sprays, since that pattern helps the vet judge what they are looking at.
Protect the Spots He Favors
While hormones settle, manage the geography. Put a litter tray where he marks most, because many bucks spray at habitual stations, and a tray with hay at that station catches much of it. Fit washable barriers on favored spots: washable mats, wipeable panels, or old towels layered over sofa corners and skirting he targets, swapped and washed on rotation so protection never lapses for a day.
Restrict access to the most sprayed room during the worst weeks rather than battling him for it, and keep his pen arrangement steady, since rearranging territory can trigger a fresh round of marking. If another unneutered male lives nearby, even in a separate pen, expect spraying to intensify while both are entire, and mention the household setup to the vet.
Expect the supporting steps to earn their keep most on visitors' days and after pen cleaning, when excitement and fresh smells stir a buck up. A spray caught by a barrier you fitted last week is the system working, not failing, and counting caught sprays against floor sprays gives you a fair measure of progress while you wait for hormones to settle after the vet visit. Keep spare barrier covers washed and ready so a soaked one is swapped in minutes rather than left in place because laundry is pending. Photograph the marked spots before you clean them if the pattern is changing, since a shifting map is useful information for the vet.
Clean Promptly and Never Punish
Clean marked spots promptly with a thorough wash that removes the scent itself, because a lingering smell reads as an invitation to refresh the mark. Blot rather than scrubbing urine deeper into fabric, wash barrier covers hot where the material allows, and let cleaned areas dry fully before he returns to them.
Never punish spraying: he cannot connect scolding with a hormonal urge, and punishment only adds wariness of you to the problem. Note that spraying is different from ordinary toileting misses, which point at litter training or tray placement instead.
