How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

Cats with dental disease, which can consist of gingivitis (gum inflammation), stomatitis (oral inflammation), tartar, and cat cavities (feline oral resorptive lesions or FORL(s)) can drool. In addition to drooling, a cat with dental disease may: Have a difficult time eating.
“Cats drool when they are in pain,” he says. “Your cat might have stomatitis, an inflammation of the mouth and lips.” Inflammations may indicate your cat has a mouth infection. “Gum disease and abscessed teeth may cause cats to drool,” he says. A chat with your veterinarian is in order.
Chattering is when the jaw shakes or quivers. It`s most often a dental sign seen in cats who have resorptive lesions on their teeth. This painful condition causes cavity-like holes in the teeth, eats teeth away or turns tooth roots to bone. Chattering typically happens when a cat eats, washes their face or grooms.
Lethargic and Drooling—Diseases or injuries affecting the mouth are common causes of drooling, and they can cause lethargy too. Lethargic and Vomiting—Vomiting is seen with problems directly affecting the digestive tract (inflammatory bowel disease, for example) and metabolic diseases like diabetes or kidney failure.
What is Feline Stomatitis? Feline Stomatitis is a condition seen in many cats where chronic inflammation affects the soft tissues of the mouth (gingiva and mucosa). It is also known as gingivostomatitis, lymphoplasmacytic stomatitis, or more accurately mucositis.
Ptyalism is excessive drooling. The symptom is associated with a wide variety of conditions, such as oral or esophageal inflammation, tumors in or around the mouth, foreign objects stuck in the mouth, stress, and poisoning. Concerned? Connect with a vet online to learn more.
Once the sensitive dentin is exposed, tooth resorption is painful and manifests as muscular spasms or trembling of the jaw whenever the lesion is touched. If your cat has tooth resorption, she may show increased salivation, oral bleeding, or difficulty eating.
In addition to these typical symptoms, cats with a calicivirus infection often develop ulcers on the tongue, hard palate, gums, lips, or nose. These cats will usually salivate or drool excessively as the ulcers are very painful.
Oral dysphagia can be caused by dental disease, tongue paralysis, paralysis of the jaw, swelling or wasting away of the chewing muscles, or by an inability to open the mouth. Cats with oral dysphagia often eat in an altered way, such as tilting the head to one side or throwing the head backward while eating.
The most common changes are weight loss, poor hair quality, halitosis (bad breath), and variable appetite, which may be associated with mouth ulcers, lethargy, and depression. Less common signs include increased drinking or urinating, vomiting, diarrhea, and anemia.
The salient clinical signs of gingivostomatitis include apparently extreme oral pain; swollen, ulcerated, and bleeding gums; lack of appetite or—if an affected cat seems eager to eat—the inability to do so; consequent weight loss; excessive salivation; blood in the saliva; bad breath; and pawing at the mouth.
Feline calicivirus (FCV) is a common differential diagnosis for cats with clinical evidence of rhinitis and stomatitis. Less commonly, FCV is associated with conjunctivitis, polyarthritis, and lower airway disease in kittens.
Symptoms of Hypersalivation in Cats

Excessive drooling (sometimes lasting for hours) Blood in the saliva. Bad breath. Inability to eat or drink.

Purring often causes cats to start drooling. Some cats may drool just a little when purring, while others may drool copious amounts when they are happy and content. This is completely normal behavior that is well within the realm of everyday cat activities, and it`s nothing to worry about.
Also known as an overbite, overjet, overshot and mandibular brachygnathism, it occurs when the lower jaw is shorter relative to the length of the upper jaw. When the mouth is closed, the teeth of the lower jaw do not occlude (align normally) with their corresponding teeth in the upper jaw.
Difficulty eating or swallowing: Cats with malocclusion may have trouble biting and chewing their food and may also struggle to swallow. Drooling: Some cats with malocclusion may drool excessively as a result of difficulty swallowing. Bad breath: Malocclusion can lead to periodontal disease, which can cause bad breath.
#1. Chattering

Behaviorists speculate that this is because your cat is frustrated that they cannot get outside to hunt prey. They also may be excited and slightly aggravated. Others say that this strange jaw movement may be your kitty`s natural instinct that allows their muscles to prepare for the act of killing prey.

The virus has gotten to the stage where it has begun attacking your cat`s nervous system, and it prevents them from being able to swallow, leading to the classic symptom of rabies, excessive drooling known as “foaming at the mouth.”
Diagnosis. A cat with lymphoma may demonstrate only very vague problems. Progressive lack of appetite, lethargy and weight loss are among the most common. Depending on which organs are affected, other signs such as chronic diarrhea, vomiting and difficulty in breathing may occur.
Cats may feel the need to protect themselves for a few reasons: They`re afraid, in pain, stressed, frustrated, or following their predatory instincts. If your cat bites and holds on or suddenly bites you unprovoked, give your veterinarian a call to make sure there is nothing physically wrong with your feline.
Diabetic neuropathy is an uncommon complication of diabetes seen more often in cats than in dogs. Signs include weakness, loss of motor control, and muscle wasting. Affected animals often have nerve dysfunction in their lower legs, which results in a flat-footed stance.
FHS can occur in cats of any age, but it is commonly seen in cats aged 1 to 5 years. Males and females are equally affected. While all breeds can be affected, Siamese, Burmese, Persian, and Abyssinian cats are more commonly afflicted.
Keep Your Sick Cat Comfortable

The cat might not like noise or high traffic, so keep him in a quiet space, away from any commotion. Provide a warm sleeping space, special food, and an easy-to-reach litter box. Make sure you don`t provoke your cat or try to rile them up. Let them rest.

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. My cat continues to scratch on furniture and carpets. He has plenty of scratching posts around the house. Please help!
ANSWER : A. Scratching is a natural behavior in cats that can be frequently frustrating for pet owners who want to keep their furniture from being shredded on a constant basis. The texture of furniture and carpet is very appealing to cats and this why they frequently choose to spend their time on this activity as opposed to playing with their own cat toys. Here are some suggestions to help curb this unwanted behavior:

1. Purchase a cat scratching post or cat tree that is covered in carpeted or textured material. Place it in an appealing spot that your cat would be inclined to spend time (eg. in the sun). You can also place catnip on the scratching post or cat tree to make your cat even more interested in the new object.

2. You can utilize double sided tape on the ends of the furniture because you cat will not like the sticky feeling and will learn to not scratch in that region. Use the tape that has a lighter adhesive in order to prevent any permanent damage. Other materials, such as aluminum foil or bubble wrap can also be placed on the furniture to discourage the scratching.

3. Keep nails trimmed short by either learning to do this on your own at home or using a veterinary technician, or groomer. Nails can usually be trimmed every 6-8 weeks.

4. Redirect the unwanted behavior. If your cat begins scratching, use a favorite or new toy to distract the cat from the scratching. Give your cat positive praise for not scratching.

5. As a last resort you can use a spray bottle full of water to spritz your cat when he or she is scratching inappropriately at your furniture. Generally, cats do not like water and this will discourage them from continuing the behavior.

Have patience with your cat because it can takes time to understand this is an unwanted behavior and that furniture is not another toy for them to use. You can always consult your veterinary or veterinary behaviorist to help with ideas or further solutions to this problem.

Q. Cat was vomiting for a few days. Took to vet, received anti-nausea medicine 2 days ago. Drinks and no longer vomits, but won’t eat. I’m worried
ANSWER : A. If your cat has been feeling nauseated, it is possible that the nausea, or just general illness is making him want to eat less. However, you can try enticing him to eat with a few tricks geared to cats.

Warming up wet foods or even bland people foods such as plain chicken or boiled hamburger can make food more interesting to cats. Cats tend to go for aromatic rather than flavorful foods, so making the food as “smelly” as possible may encourage your cat to take a bite. Bland foods are also good for helping to soothe upset stomachs, which may still be happening if your cat had recently had a vomiting episode.

However, if enticing your cat to eat does not work, or he continues to refuse to eat any food, it is best to contact your local veterinarian for more care and testing. Cats can become very ill if they refuse to eat for more than a few days, and finding the underlying cause can help your cat feel better.

Q. Would a male cat be affectionate to another male cat or would a female be more affectionate
ANSWER : A. The sex of the cats is less important than the personality of each cat. If the cat you have at home is already a strong-willed cat, another cat like that will lead to a lot of confrontations as they both try to be in charge and an older cat shouldn’t be matched with a rambunctious younger cat. If you keep in mind what your cat’s basic nature is, you’ll find a good match. I’ve always had multiple cats and rarely have a problem integrating a newcomer.

Q. How should I interpret my cat’s tail movements?
ANSWER : A. Our feline friends express themselves in many different ways, including through the use of their tails. Most pet owners pay close attention to a happy or excited dog, but they are sometimes less attentive to the posture and movement of their cat. Here are some of the most common cat tail behaviors, and the underlying emotion behind each action:

A flicking tail: Many anxious, nervous or stressed cats will hold their tail in a low position and flick it quickly back and forth. This is often referred to as angry tail, and a pet owner or veterinarian should be on guard for any possible aggressive or defensive activity. If a cat is moving their tail slowly, and not exhibiting the flicking motion, then this cat is at a much calmer state.

Vertical position: Most of the time when a cat is holding their tail in a straight, vertical position this is indicating curiosity and a playful mood. A cat chasing after a laser pointer or playing toys will often have their tails in a vertical position showing their enjoyment. This position also helps with balanced movements. In contrast, if the tail is in the vertical position and the cat’s back is arched with pinned back ears then this could demonstrate a feeling of being threatened and thus result in defensive or aggressive behaviors.

The Tucked Tail: Similar to a dog, a tucked tail often indicates submission or fear. Your cat is conveying upset feelings and should most likely be left alone. This tucked tail appearance can also make a cat look smaller and less threatening to an aggressive cat.

The Tail Twine: Cats will often hook their tail around another cat’s tail, owner’s legs or other objects to show a friendly and affectionate nature. They are also trying to indicate whether they want to receive affection from their owners, be fed or have playtime.

The next time you are home with your feline companion take note on how they express themselves through their tail movements, their ears, body posture and vocalization. You can start to better understand their needs and wants, in addition to what makes them uncomfortable or happy. Cats will surprise you with their array of emotions and varied expressions they can express.

Q. We have two female cats who are sisters. One was just diagnosed with generalized lymphoma. Is there risk of being contageous? What kind of food
ANSWER : A. Lymphoma is a cancer and not a bacteria or virus, so it cannot be spread from cat to cat via contact. However, if your cats are related, they may both be genetically predisposed to getting the same type of cancer. Feline lymphoma can also sometimes be caused by the Feline Leukemia Virus (FeLV) or Feline Immunodeficiency Virus (FIV) which CAN be spread from cat to cat. The spread of these viruses is usually through bite wounds, saliva or fecal and urine matter, and the chances of spread among two amicable cats is lower, however testing both cats is always good.

As lymphoma can cause a decrease in appetite, sometimes the best food is one that will keep your cat on her normal eating routine so that she keeps her weight and energy up. Enticing her to eat by warming up wet foods, or even moistening and warming dry foods may encourage continued normal eating and may prevent weight loss from loss of appetite. A high-fat, high protein and low carbohydrate diet (such as a grain-free diet) may also help by providing a more calorie and nutrient dense meal so that every bite is beneficial.

Q. I have a cat with that virur (aids) could u tell me about her disposition and care
ANSWER : A. Thanks for your question.

Unfortunately the discussion about what you asked has no straightforward answers and can be quite complex.

First thing that I would double check, considering that your cat is very young, is whether she is really infected. It is important to remember that kittens born to FIV-infected queens will receive antibodies from the queen via the milk, and so will test positive early in life though they may not be infected. Kittens with a positive test result should always be retested when they are 5-6 months of age.

Many FIV infected cats are able to live happily with the virus for a long period of time, and indeed the virus will not necessarily ever cause clinical disease.

Different factors will influence the onset of disease in your cat including:

– The ”subtype” of FIV your cat is infected with,

– Her immune response

– The presence or absence of other infectious agents.

To maintain a good quality of life for your cat, I will give you these general guidelines, but you will then find certainly helpful to speak with your veterinarian for specific cases.

– Some antiviral medications used in human patients with HIV infection have also been shown to help some cats with FIV infection. Interferons may have anti-viral effects and modify immune responses. A recombinant feline interferon (feline interferon omega) is available in some countries. Down side is the cost usually.

– Keep your cat away from other cats and possible source of infections;

– Maintain good quality nutrition;

– Keep your cat indoor if possible regularly checked by your veterinarian;

– Keep your cat away from non-infected cats.

Q. I found a large amount of pee from my unfixed male cat and it had blood in it. I notice later what looked similar to crystals in the same puddle. Help
ANSWER : A. You should have your cat examined and a urinalysis done immediately. Some cats do form crystals in their urine which leads to bladder inflammation,look in the urine, pain and in creased frequency of urination. The specific problem with male cats is the narrow width of the urethra through which the urine passes. Make cats have a very narrow urethra unlike female cats. The crystals, blood and other “sludge” that forms in the bladder when a cat has cystitis can cause a blockage in male cats and this is an emergency. A urinalysis can determine the extent of the problem and allow your vet to recommend appropriate treatment before it becomes an emergency. Your cat should be seen today.
