Is your bunny a male and is he neutered? Tiny pee spots could be from spraying. Though I think females can spray as well.

Spraying can happen anywhere — It is a very effective technique by unfixed rabbits to spread their scent around. They will not do it all the time (they pee normally too), but it’s a method of territorial marking. Unfortunately, if it is spraying, the only thing to do to stop it is have your rabbit neutered by a rabbit-experienced vet. It is a hormonal behavior, so as long as he is intact, it will likely happen. He may stop over time when he covers it enough, but unsure.

If you’re seeing small drips of pee on the carpet, it may be from spraying, especially if your vet ruled out a UTI (urinary tract infection). Do the pee spots form a pattern, like a line or anything? Whether a rabbit sprays does not mean anything towards if he/she is aggressive or not.

It sounds like hormonal marking to me.  Since he’s not neutered, that’s most likely, and he’s at the age when hormones are raging. Ruling out a UTI would be good though.

You can try removing the carpet and see if that helps, sometimes bunnies will mark more on soft surfaces.

Neutering should fix the problem assuming it’s not a UTI. Is there a specific reason why you’re hesitant to neuter?

I get that. 🙂  They shouldn’t be put through unnecessary surgeries. And your bun sounds to be well behaved as far as hormonal behaviors are concerned, apart from the marking. Most rabbits will act a lot more hormonal until they’re fixed. Often the urge to mate can become a major source of stress for them, which is a good reason to get them fixed for their own benefit rather than just for the owner’s convenience. Same with spaying females to eliminate the high cancer risk.

Generally I would recommend getting a male neutered even if he’s well behaved. They might start to act hormonal later in life, or the owner might decide to try and bond them to another rabbit and at that point they might be too old to make it through the surgery safely.

I hope you can find a vet you can trust, I know that can be difficult. The house rabbit society has a list of vets that can get you started.

That’s a good point you make Hazel, rabbits can still go wildly hormonal later in life!

Our bunny Breintje used to live in my boyfriend’s room on campus, and my boyfriend never noticed humping and spraying behaviours.

Breintje was 2,5 years old when he came to my house, and that sweet playful bunny turned into a raging sex offender who peed everywhere. He had a lot of frustrations and made a mess out of things. I couldn’t leave a piece of clothing or a pillow around him without him humping it, and he even went for my knitting projects 🙁 That was a nasty sticky surprise, and the reason why I told my boyfriend that we needed to get Breintje neutered.

My boyfriend was afraid to neuter him because he heard bad stories about surgery anaesthetic gone wrong. The person who told him those stories used to be a vet’s assistant in the 80’ies, and rabbit veterinary science has improved a lot since then.

We talked it over with an expert rabbit vet, and Breintje was deemed healthy enough to be neutered. He soon turned back to normal again 🙂

That’s a tough situation! You might notice some fluctuations in hormonal behaviors with the season, as well as with age. It’s great that he isn’t fully spraying, because that can be so annoying to deal with (I had a completely adorable young un-neutered bunny spray me in the face!).  Even if you can’t neuter until later in his life, it should still help then, so no need to stress out too much at the moment. Searching for “exotics vets” can usually help find vets that are experienced with rabbits.

I think I already mentioned this, but it might help to remove any soft surfaces (carpet, blankets, etc) in the area where he’s been peeing. I like to have a solid surface in the area right around litter boxes as it helps with box habits and makes clean-up of accidents easier.  I’ve also had buns that will pee or poop where-ever there is hay, so I would have to make sure that they could only reach their hay while sitting in their litter box. When he does have accidents, try to mop up the pee with a paper towel and put it in his litter box, then clean the area with a 10% vinegar solution to neutralize odors.

Not sure what’s available in your area, but there are products for puppies that are theses washable blankets that are water-proof on one side (in the US they are either called puppy-pee pads or whelping mats). If things don’t get better, that might make it easier to protect the floor and keep things clean long-term. There are also disposable pee-pads, but they might not be as nice to use long term.

OH, I also JUST made the connection that you posted about your bunny chewing the cage bars at night? And posted a picture of his cage set up there?

If that is still the current cage, that litter box looks too small for him. He might be accidentally peeing over the side, or just not wanting to go in because it’s too small. (Those corner boxes are sold for rabbits but they are really too small for almost all bunnies!)

I would try getting a larger box (lots of people use large cat litter trays, or those low plastic storage bins that fit under beds). Add his hay rack at one end so he can’t get to his hay without hopping in the box.

Hope that helps!

Just to note, if you have access to a rabbit experienced vet, 3lb is not too small to neuter safely. My rabbit is 2.5lb at full size, and he was neutered when he was at 2lb.
