Stress is major cause of inappropriate urination in cats. Factors causing stress in cats can be moving house, the introduction of a new family member (pet or human), a neighbours cat roaming your garden etc. Helping your cat overcome these stresses may well result in the inappropriate urination stopping, however this isn't always the case. Sometimes the behaviour can become so ingrained in the cat that even once the stress has been removed, the behaviour continues.
Removing the cause of the stress is naturally something you will need to tackle. So have a good think about what may be causing the stress. Has the behaviour come on suddenly? If you can find a cause for the stress, you have a much better chance of taking steps to help your cat overcome this stress and hopefully stop the behaviour. Feliway is a synthetic facial pheromone, facial pheromones induce feelings of comfort and safety in cats and bring down stress levels. Therefore Feliway can be used to mimic this pheromone.
If this is the case it is a good idea to seek advice from your veterinarian as to how to re-train your cat. Some cat owners have had great success using Rescue Remedy on their cats, although this isn't advisable until you have spoken to your vet.
A good rule of thumb is one litter tray per cat, plus one spare. So if you have two cats, you should have three litter trays. Cats are fastidiously clean animals and if there aren't enough trays in the house, or the trays aren't cleaned often enough, they will find another spot to go to the toilet. I like to scoop out solids from litter trays twice a day and completely replace the cat litter once a week.
Keep trays within proximity to food and water bowls, but not next to them, cats don't like to go to the toilet near where they eat, would you?
Size is another important factor, obviously a Maine Coon is going to need a larger litter tray than a 10 week old kitten. I like to start out small for kittens, and once they're around six months of age, introduce a full sized litter tray. For some larger cats, you may opt for an extra large plastic container instead. See here for more information on choosing a litter tray.
The first thing you should do is take your cat to the vet to rule out any medical reasons for this inappropriate urinating on your bed. Some causes of cats urinating outside of the litter tray include urinary tract infections, bladder stones, kidney stones, declawing pain and discomfort from arthritis.
Your veterinarian may also recommend anti-anxiety medications in the case of stress related toileting. There are several drugs available and your veterinarian will be able to prescribe the best one for your cat.
What you need to remove cat urine from a bed:
Empty spray bottle.
1 part white vinegar.
2 parts warm water.
Add to bottle, shake well.
2 tablespoons bi-carb soda (baking soda).
15oz hydrogen peroxide.
2 squirts hand soap.
Add to bottle, shake well.
How to remove cat urine from a bed:
If the urine has dried and you are having problems locating the soiled area use a blacklight. Cat urine will glow green, making it easy to find the problem area. You should be able to purchase a blacklight from your hardware store or eBay.
If the urine is still wet, blot up as much as you can with paper towels. There are many commercially available products on the market designed to remove and neutralize cat urine odour. Some of these products come in powder form, so can be easily vacuumed off, others are liquid (often as a spray), so once you have applied it, it can be dried with the aid of a hairdryer.
Apply baking soda to the wet urine stain. This will draw out the urine. When the baking soda turns yellow from the urine, remove and apply some more. Repeat until the baking soda stays white. If possible, leave on the mattress overnight. The following day, vacuum it off.
White vinegar is a time tried and proven ingredient that aids in removing both urine stains and the odour. Combine one part distilled white vinegar to two parts warm water to create a spray. Remove as much urine/spray as you can using a paper towels. Mist vinegar spray over areas of cat urine and rub with a paper towel. An alternative method is to mix the solution in a bucket and dip a clean cloth into the liquid. Rub the stain with the vinegar solution. After the vinegar dries, wipe away both solution and stain with warm water.
Mix 15 ounces of hydrogen peroxide, two tablespoons of baking soda, and two squirts of liquid hand soap in a plastic container with a plastic spoon. Discard after use. Apply this solution to cat urine stains or odour areas, and then rinse away with warm water.
How to prevent your cat urinating on the bed:
Naturally you will have to wash your bedding. Washing detergents used for nappies are the best products to use in this case.
Keeping your bedroom door closed is the obvious solution although many cat owners may be reluctant to shut their cat out of the bedroom.
Plastic carpet runners turned upside down will act as a deterrent, cats dislike the feel of these. So, whenever the bed isn't used put these over and hopefully in time your cats habit will be broken.
Try putting a fitted plastic sheet over your mattress. These are used with young children who are toilet training, to ensure any accidents don't seep through to the mattress.
