Rabbits are no more harmful to human beings than cats are PLUS rabbits do not carry any diseases that can be transferred to humans. If done in time, just like with cats, neutering will prevent a male rabbit from spraying. However, just like cats, if a male rabbit has started spraying having him neutered will stop the spraying in 50% of the cases.
Most female cats do not spray, but those that do will only do so if they are in heat or highly agitated.
You can always talk to your vet, or your cat can live outside.
Female cats typically start spraying around 6 to 12 months of age.

Hi there...cats can reach sexual maturity between 5-7 months of age. Male cats should be neutered before they reach sexual maturity to avoid instinctual urine spraying. Spraying which has been ongoing for a length of time then it becomes habitual and difficult to stop.
Stray cats can be dangerous due to the possibility of carrying diseases from hunting. To stop a stray cat from coming in the home through a cat flap with the intention of spraying in the house, it is best to contact animal control to remove the animal.

For indoor plants, try spraying a little vinegar in the soil. I know that for outside plants, you can drop mothballs around them to keep cats out.
Male cats typically start spraying as they reach sexual maturity, around 6-12 months of age. Spraying behavior may continue throughout their adult life if they are not neutered. Neutering can significantly reduce or eliminate spraying behavior in male cats.
She's probably in heat. I'd get her spayed either way. There are too many homeless cats in the world to be bringing more into it. Make sure you clean all the areas she's sprayed with an enzyme cleaner you can find at a pet store, or even after you get her spayed she'll keep doing it.
In most cases, they don't. This is because other cats consider a neutered cat ''genderless'' which may seem kind of crazy in real life, but that's actually true. Neutering your cat will decrease the risks of it getting into cat fights, and will stop it spraying.
