Yes, rabbits spray urine, and both males and females do it. Spraying is a normal territorial and reproductive behavior driven by hormones. It typically begins when a rabbit reaches sexual maturity, around 3 to 6 months of age, and is one of the most common behavioral complaints among rabbit owners.
Why Rabbits Spray
Spraying serves two main purposes: marking territory and signaling sexual availability. Rabbits spray urine around their living space to communicate boundaries to other rabbits, essentially claiming ownership of an area. Sexually mature males also spray as part of courtship, sometimes directing urine at females (or at you) as a display of interest. The University of Miami’s rabbit care guide describes spraying as “a sign of love, but still…”
Environmental changes can also trigger spraying. A rabbit entering a new home, being introduced to a new companion rabbit, or sensing an unfamiliar animal in the household may start spraying to reassert its territory. Even a rearranged living space can set it off.
Males vs. Females
Intact males are the most frequent sprayers. When sex hormones kick in, male rabbits often begin mounting objects, producing a strong musky odor, and spraying urine on vertical surfaces, other animals, and sometimes their owners. The urine itself tends to smell more pungent in unneutered males.
Females spray too, though it’s generally less frequent and less intense. Unspayed females are more likely to spray when they sense other rabbits nearby or during hormonal cycles. Both sexes can spray with surprising accuracy and distance, sometimes hitting walls, furniture, or people from several feet away.
Spraying vs. a Medical Problem
Normal territorial spraying looks deliberate. The rabbit lifts its tail and projects urine horizontally, often aimed at a specific target. It happens in bursts and is clearly different from regular urination in the litter box.
If your rabbit is urinating outside the litter box but not in that characteristic spray pattern, something else may be going on. Signs that point to a urinary tract issue rather than behavioral spraying include blood in the urine, straining or pushing while urinating, crying out during urination, unusually foul-smelling urine, or urinating in small amounts near (but not in) the litter box. Increased water consumption can signal a kidney problem. These patterns call for a vet visit rather than a behavioral approach.
How Neutering Reduces Spraying
Neutering or spaying is the single most effective way to reduce or eliminate spraying. Because the behavior is hormone-driven, removing the source of those hormones addresses the root cause. Most rabbit owners see a significant drop in spraying after the procedure, and many rabbits stop entirely.
The change isn’t instant, though. After surgery, it takes several weeks for residual hormones to clear the rabbit’s system. The Rabbit Welfare Association notes that hormonal behaviors “should settle down in a few weeks,” and the House Rabbit Society recommends allowing about a month for better behavior to emerge. During that window, your rabbit may still spray occasionally. If spraying continues well beyond a month post-surgery, the behavior may have become a learned habit rather than a purely hormonal one, and you may need to revisit litter training and environmental management.
Managing Spraying at Home
While waiting for a neuter appointment or during the post-surgery hormone wind-down period, a few practical steps help contain the mess. Limiting your rabbit’s free-roam area reduces the territory they feel compelled to mark. Placing litter boxes in spots where spraying tends to happen can redirect the behavior. Covering walls and furniture near those areas with washable plastic sheeting saves you from stain damage.
Cleaning up spray quickly is important because the scent encourages repeat marking. Rabbit urine contains more calcium than dog or cat urine, which is why it often leaves a white, chalky residue on hard surfaces. Full-strength white vinegar is the best first-line cleaner. Spray it directly on the soiled spot and let it soak for five to ten minutes on fabric or carpet, or one to two minutes on tile and linoleum, then blot it up. The vinegar smell fades fast and neutralizes odor without leaving harmful residues.
For set-in stains or persistent odor, enzyme-based pet cleaners break down the odor at a molecular level. Products marketed for pet urine (like those found in the pet aisle of most stores) work well on rabbit spray too. The key is choosing an enzymatic formula rather than a simple fragrance-masking spray, since rabbits can still smell their old marks through perfumed cleaners and will respray the same spots.
