Most air sprays are not good for animals, especially rabbits since they are sensitive. You have to be very careful in selecting a spray or disinfectant, even if the product says it's animal safe. Most "animal safe" products were tested in certain environments and only around certain animals, so that leaves a wide range of circumstances in which the product can easily harm your pet.
Products that are made specifically for animal use (and particularly rabbits) are things like Quats and Vanodine. These solutions are highly effective in not only eliminating all forms of bacteria, viruses, and fungi, but they also leave a fresh scent behind. We've used the lemon quat in our rabbitry a couple of times a week and if you walked into the rabbit shed, by the scent alone, you'd never know rabbits inhibited the place, lol.
