I have 8 bunnies living inside and they do not smell...and it's not because I'm "immune" to the odors. I would guess that whoever told you this, IF they had a bunny at one time, didn't take good care of it.

The litter boxes should be kept cleaned. In summer I will do that twice a day!!!! I also put baking soda in the bottom of the litter box then the litter. I do not use newspaper to line the litter box with because I have found that that is a contributing factor to litter box smell. Rinsing the litter box out with a small amount of white vinegar will neutralize any odors. The vinegar is also good if there is a urine accident on hardwood, tile or lineolum floors. The vinegar smell dissapates very quickly.

Bunnies are highly suspectible to reproductive cancers, esp. the females. Another benefit of spayed and neutered bunnies is that their urine is less strong, so on top of spaying/neutering being very healthy for them it cuts down on litter box odor too. BE sure however that you have a vet specializing in bunnies.

Good luck with your bunny and don't let anyone talk you out of keeping the bunny inside. Living indoors also leads to a longer, healthier life and the more you interact with a bunny, the more charming, playful and loving he will become.
