So, can cats share a litter box? If you have multiple cats, they may be comfortable enough with each other to share the same litter box. However, there are several reasons, including territorial behavior, why some experts would advise at least one extra litter box in your home.
Cats stop using their litter boxes for a variety of reasons, including issues with the box or litter, dissatisfaction with the placement or number of boxes, changes in the environment inside or outside the house (e.g., a new pet in the house, feral cats prowling around outside), and undiagnosed medical conditions.
Young males (3-24 months) have an especially strong need for a “buddy”. While guardians of rambunctious young males often hesitate to take on another cat, those who take that “leap of faith” and get another young male are generally delighted to see how much the “boys” enjoy each other.
A little known fact is that kittens in a single litter can have different fathers. There could even be as many fathers as there are kittens! The ability to produce a litter of kittens fathered by more than one tom cat is called superfecundation.
If you have a young cat at home and want a second, consider adopting one kitten of the opposite sex, as same-sex cats are much more prone to fight each other for dominance. Your resident cat will still be young enough to recall having fun with her littermates, and the new kitten will be more than happy to oblige.
Give Each Cat Their Own Food Bowl – They Don`t Want to Share! Although having cats share a bowl is often easier, saves space, and creates fewer dirty dishes, there are so many reasons cats need their own bowls! Eating separate is instinctively how cats eat most comfortably.
For the most part, all experts agree…the litter box should be scooped 1-2 times each day. “Litter boxes should be scooped at least once or twice a day, and it`s even better if you can get to it as soon as your cat has finished his business,” said By Dr. Stephanie Janeczko in this featured post on Petfinder.
Any cat can exhibit marking behaviors, but it tends to occur in male cats that have not been neutered. Although hormones may be behind urine marking, stress and anxiety also are causes.
In this study, no overall preference was seen for covered versus uncovered litter boxes. When individual cats were assessed, 70% showed absolutely no preference (i.e. used both boxes equally), 15% used the covered litter box more significantly, while 15% used the uncovered more than the covered. Pretty even results.
Single kitten syndrome is the idea that young kittens, when raised with other young kittens and cats and then adopted into a home by themselves, can become aggressive, anxious, stressed, and even develop behavioral issues like inappropriate chewing/scratching and inappropriately using the litterbox.
It has been known for dad cats to bond with their kittens, and even help the mom to raise them. Nevertheless, experts advise pet owners to keep male cats away from the mom and newborns, or supervise them at all times until the kittens are less vulnerable.
Don`t worry too much about the gender of the cats involved. Age and temperament are the most important factors. Adult cats will usually accept a new kitten much more easily than they will accept a new adult cat. Cats are territorial, and your cat may resent an adult feline intruder.
Cats Can`t Taste Sweetness, Study Finds : NPR. Cats Can`t Taste Sweetness, Study Finds Some scientists have long suspected that cats, which are strict carnivores, are “sweet blind.” Now there`s proof: Cats lack the receptor for sweetness. The discovery opens a window on what taste is for and how it evolved.
Females can be mated by more than one male within a short period of time and this includes relatives, even her father and brother. Mating doesn`t take long between cats, so it`s easy to be caught out!
Will two male cats get along? Well, that depends on the cats. Contrary to popular belief, two male cats will not necessarily fight each other to the death. Cats that have lived on the streets and have had to defend themselves will be more aggressive once rescued and placed in a home.
Pairs Make Happier Pet Owners

Because two cats tend to live happier and healthier, there`s less chance of bad or destructive behavior, which means less damage to furniture and belongings, and happier pet owners. But the best reason of all to adopt a bonded pair: double the affection.

Separate Food and Water Bowls

Cats also do not enjoy the scent of food while drinking water. In addition, they are turned off by food particles in their water. Therefore, keep cat food and water bowls in two separate locations.

The easiest way to stop cats from eating each other`s food is to feed at set times and monitor them. Put down cat food at the same time at the same place every day and watch them eat. Your furry friends will soon learn when meal time is and will very likely be sitting behind you watching your every move.
Your cat could be just trying to maintain her scent in the box, even though you`re cleaning it. Animals usually go to the bathroom to give us a message. If it`s outside the litter box, they could be stressed or in need of a clean place to go.
But cats are born with the instinct to dig and cover their waste. Theoretically, she says, if you place an appropriate litter box in a room, a cat or kitten will use it. Stray cats transitioning from outdoor to indoor life also know what to do, but they might insist on using your houseplants rather than the litter box.
How often you replace the litter depends on the number of cats you have, the number of litter boxes and the type of litter you use. Twice a week is a general guideline for replacing clay litter, but depending on your circumstances, you may need to replace it every other day or only once a week.
The best way to clean a litter box is to dump the entire box and soak it in hot water for a few minutes at least once a week. It is not necessary to use detergents or cleaning chemicals, as hot water will generally do the trick.
As a general rule, cats are sensitive when it comes to smells, but there are a few scents they hate that might just surprise you. They can`t stand citrus and as much as you might love the smell of fresh herbs, cats hate rosemary and thyme. Banana and mustard are a big no-no too, as well as lavender and eucalyptus.
In the cat world, a moderate degree of licking is part of normal grooming behavior. For example, a male or female cat may lick the genital area after urinating as a means of cleaning the area.

the most relevant questions and answers related to your specific issue

Q. I have a cat that defecates in the litter box but always urinates outside the box. It is very annoying.
ANSWER : A. Inappropriate elimination in cats is often a behavioral problem rather than a medical problem, so the first step is to have him seen by your vet to eliminate any kind of illness or condition as a cause for his eliminating outside the box.

If medical issues are ruled out, take a look at other reasons. Has there been a lot of unusual activity? Has you cat been left at home or boarded? Is the litterbox in a busy area? Has anything happened recently in this area to make him reluctant to use it again? Is there another cat, pet or person that is preventing him from getting to the box? Have you changed it from a hooded to an open box, or vice versa? Is it big enough? Have you changed the type or brand of litter? Is there something attractive about the spot he uses? Cats dislike disturbances to their routine and may act out to express their dissatisfaction.

The general rule is one litter box per cat in the household, plus one. That way each cat can have a place of their own to go in case the box is occupied or another cat has claimed it as territory. They should be scooped daily, if not more often and changed completely weekly, washed with soap and water only. You can offer one kind of litter in one box and another kind in another to see if there is a preference. I don’t recommend the crystals, it makes a hissing sound when wet that startles some cats and make them reluctant to use it again. The litter boxes should be located in a quiet, low-traffic area so that the cat can use them in peace. Make sure any other pets or people aren’t giving them a hard time around or in the litter box. It may take some investigation and experimentation to find your cat’s preference and accommodate him so that everyone is satisfied with the situation. And, when cleaning up pet accidents, don’t use any cleaner containing ammonia. This leaves behind a scent similar to urine.

Q. My cat will not stop going to the toilet on my carpet, bed, washing pile etc.. Also uses its litter box occasionally? I don’t understand why this is?
ANSWER : A. Inappropriate elimination in cats is often a behavioral problem rather than a medical problem, so the first step is to have him seen by your vet to eliminate any kind of illness or condition as a cause for his eliminating outside the box.

Q. My cat started to pee outside the litter box. What should I do?
ANSWER : A. Inappropriate bathroom use in cats is often a behavioral problem rather than a medical problem, so the first step is to have him seen by your vet to eliminate any kind of illness or condition as a cause for his defecating outside the box.

Once medical issues are ruled out, it’s time to take a look at other explanations. Has there been a lot of activity that wasn’t normal? Were you away and your cat was left at home or boarded? Is the litterbox located in a busy area? Has anything happened recently in this area to make him reluctant to use it again? Is there another cat, pet, or person that is preventing him from getting to the box? Have you changed it from a hooded to an open box, or vice versa? Have you changed the brand of litter or kind? Or is there something about the spot he has chosen to use that is attracting him in some way? Cats dislike disturbances to their routine and may act out as a way of expressing their dissatisfaction.

The general rule of thumb is one litter box per cat in the household, plus one. That way each cat can have a place of their own to go in case the box is occupied or another cat has claimed it as territory. They should be scooped at least daily, if not more often and changed completely on a weekly basis, and washed with soap and water.

You can also offer one kind of litter in one box and another kind in another to see if there is a preference. I don’t recommend the crystal kind, since it makes a hissing sound when wet that can startle some cats and make them reluctant to use it again.

Q. My cat is pooping outside of the litter bix. He is 2 1/2. He did this as a kitten. It stopped then started about 3 months ago. Litterbox is clean.
ANSWER : A. Inappropriate elimination or house soiling can be a frustrating problem but with a bit of detective work on your part, there is hope. First, before deciding that this is a behavioral issue, any medical problems (diarrhea, constipation, fecal incontinence, pain on defecation, etc.) need to be ruled out and/or treated. If your cat receives a clean bill of health from your vet but is still eliminating outside the litterbox, then we need to consider that something about the box itself might be aversive to your cat. Cats can be quite finicky about their litterbox and toileting habits. Below I have listed common recommendations and cat preferences for litterbox use. Review the list and make any changes that could account for your cat’s aversion to defecating in the litterbox:
* Soft, fine-grained clumping litter (vs, coarse-grained, non-clumping litter)
* Unscented
* 1 – 1 1/2 inch depth (especially older cats or cats with hip problems)
* Larger pans (especially for large cats) – want to get whole body inside – poop just outside the box might mean the box is too small
* Open, non-hooded
* At least one shallow side to get in and out easily
* Easy to get to – not hidden away, preferably in areas they spend time in or near – and not near appliances that make scary, unpredictable noises (washers, dryers, refrigerators)
* Scoop minimum 1X/day – preferably 2
* Clean the litterbox with soap and water and put in fresh scoopable litter at least once/month (instead of just continuously adding)
* Some cats prefer to urinate in one box and defecate in a separate box, so you may need 2 boxes even if you just have 1 cat. Multi-cat households should have 1 box/cat plus 1 extra.

Q. My cat seems to have lost control of her bowels and no longer uses her litter box even to urinate. She is 5 or 6 yrs and is in good health otherwise
ANSWER : A. If your cat has had a sudden change in litter box habits, it is always a good idea to rule out any underlying issues with a wellness check from your vet. Bringing in a urine and stool sample if possible can also help as tests can be run on these samples to check for common infections or parasites. If these are present, treating them usually helps resolve the problem of not using the box.

Loss of bowel control usually results in dribbling of feces or urine rather than complete accidents. If you are seeing this, it is possible that an injury to the hind end or problem with the nerves or muscles is happening and should be looked at by your vet.

If the accidents are complete (full amount of stool, big puddle of urine) your cat may be choosing not to use the litter box due to illness, a too-dirty litter, litter pans that are too tall (which may make older cats have a harder time getting in and out), or a litter substrate that was changed too suddenly. Sometimes, changing the environment your cat’s litter box is in by lowering the sides, moving food and water dishes away and returning back to a previously liked litter can help.

In any area of an accident, an enzymatic cleaner should be used. These break down urine and stool particles, making it so that your cat is less likely to be attracted to going there again. Moving stools to the litter box can also entice your cat to start going there again.

Q. Why do cats meow?
ANSWER : A. Cat parents often wish they could better understand what their favorite feline friends want or desire. A cat’s meow can be interpreted in many different ways and can indicate an array of feelings and needs. Here are some of the most common reasons for your cat’s vocalizations:

1. Greeting- Many cats will meow as a greeting when you enter your home or walk into a room. Cats will also meow at another cat or animal in the household to extend a hello and acknowledge the other animal’s presence.

2. Attention – An exuberant meow followed by leg rubbing or another attention seeking behavior may indicate your cat is looking for some quality time spent together. Some petting or rubbing behind the ears may be in order.

3. Hunger – A meowing cat is often a hungry cat. This is one of the most common reasons for a cat to vocalize to their owners. A cat will meow to get your attention at feeding times or even when they want extra food.

4. Sickness – A sick or hurt cat may begin to meow excessively, warranting a visit to the veterinarian. There are numerous reasons for a cat in distress to meow—whether it is related to an upset stomach, an injured leg or a urinary blockage. These meows should be carefully investigated.

5. Entering or leaving – Most cats will vocalize when they want to be let in or out of a room. You may notice when you are in the bathroom or behind the closed door of a room that your cat begins to meow, scratches at the door, and often reaches its paw under the door. This is a clear indication that the cat wants to be where you are.

6. Angry – An agitated cat may meow to warn their owner or another household pet that they are upset and would like to be left alone. This angry meow may increase in sound volume as the cat becomes more stressed or agitated. Often a cat will exhibit this type of meow at the veterinary office when they are unhappy with their examination or restraint.

Each feline is different and so are their vocalizations. Learn to understand the variety of meows your cat uses on a daily basis. This will help you develop a better relationship with your cat and help them live a more trusting and happier life.

Q. Cat is deficating on rugs, not litter box. Has never done this until this year. We drove from NY to FL, could there be a connection?
ANSWER : A. Sudden changes in bowel or litter box behavior can be caused by both behavioral or medical reasons. Scheduling a wellness exam with your local vet to rule out any problems (and also to bring in a stool sample) is the best first step. Problems such as digestive upset, constipation, diarrhea or even arthritis in older cats making it harder to get into the box can all cause this problem.

If your cat checks out healthy, it is possible that stress such as another person or pet in the home, age, or environment are causing the problem. Make sure that the litter used is the same, and if it needs to be changed that it is done gradually- cats are very picky about what they like as litter. Making sure bedding, food and water are not too close to the litter can also help as cats do not like to potty near these objects usually. For arthritic cats, a step or lowered box can make getting in and out easier to allow for proper use of the box. Keeping the box clean is also a must for cats.

As for cleaning up accidents, using a product such as an enzymatic cleaner may be helpful. These products break down urine and stool particles left in the accident area, and may deter your cat from using the spot as a bathroom again.
