Experienced and professional animal trainer provide their insights in answering this question :
A. It could be that he has suffered a head injury, or that he has a congenital problem or that he is intoxicated, or perhaps that he has a deep ear infection. The symptoms you describe are neurological, and potentially there are several possible causes that carry different prognosis. I have seen kittens with head trauma improving with the symptoms you describe, but pain relief is really important to be provided. I would suggest to have the kitten checked over.

How to Identify Common Pet Problems ?

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

Vestibular disease is when a cat suddenly develops incoordination, falling or circling to one side, involuntary darting of the eyes back and forth (nystagmus), a head tilt, and often nausea or vomiting. These clinical signs usually appear suddenly, often in less than an hour.
When the vestibular system is not working properly, cats will often show signs such as circling (to one side), falling or rolling to one side, a head tilt, and nystagmus (beating of the eyes back and forth). An inner ear infection is one common cause of vestibular disease in cats.
It`s likely your cat is experiencing an issue with her vestibular system. The feline vestibular system is essentially the balance center of her brain. When something is amiss in this complex web of nerves and synapses, she`s likely to become dizzy, disoriented, and have trouble with muscle coordination.
The signs that your cat may be suffering from a neurologic disorder include: reluctance or refusal to use its litter box; altering the way it interacts with its owner and others; and a noticeable change in its gait and apparent sense of balance. An affected cat, says Dr. Dewey, may suddenly “flop down and flail around.
Vestibular Disease

Your cat may also walk in circles, tilt its head to the side, or move its eyes back and forth very quickly. Ear infections, bacterial diseases, tumors, or exposure to toxic drugs can be responsible for the unusual behavior, although it may not always be easy to determine the cause of the disease.

The signs and symptoms of a cat stroke

Sudden collapse. Head tilt. Blindness. Stumbling.

The most typical symptoms are jerky or uncoordinated walking, swaying from side to side when trying to walk, a goose-stepping gait called hypermetria, mild head tremors, and/or intention tremors. Intention tremors are tremors that occur when the kitten intends to make some sort of movement.
The cat may be experiencing a transitory problem with its vestibular system—the complex arrangement of nerves and other components that governs its sense of balance and coordinates the movement of its head and eyes. Such a disorder and its alarming manifestations are typically temporary and ultimately harmless.
Symptoms of Fading Kitten Syndrome

The kitten`s face may start to look gaunt and triangular if it is not getting adequate nutrition. Fading kittens may also fail to gain weight normally (or even worse, lose weight), which can be determined by weighing the kitten at least once a day.

Common signs of a sick kitten include: lethargy, weakness, decreased or lack of appetite, less interest in playing, sleeping more, vomiting, diarrhea, weight loss, trouble walking, and less interest in their owners, companions, and toys. The very first sign many sick kittens show is not eating.
The typical signs of brain injury in a cat include altered consciousness that may signal bleeding in the skull, decreased blood flow to the brain, or fluid causing swelling within the brain itself.
Like people, cats can suffer from mental health issues, such as depression and anxiety. Find out how you can tell if your cat is struggling emotionally and what you can do about it.
Seizures in cats are characterized by sudden surges of uncontrollable muscle activity, often described as fits or convulsions. They can last for as little as a few seconds or up to a few minutes, with some even lasting for hours. They`re caused by a temporary disturbance of the brain`s normal functions.
If your cat is experiencing a stroke, one or more of these symptoms may suddenly appear: Head pressing. Head turning or tilting. Loss of vision.
Cat seizures manifest as unusual behaviours such as collapse, twitching, gnashing of the teeth and tremors. During a seizure, there are sudden, abnormal electrical impulses that disrupt the normal processes in the brain.
These kittens may have cerebellar hypoplasia. Often referred to as `wobbly kittens` or `wobbly cats`, cerebellar hypoplasia is an unusual neurological disorder as a result of interrupted development of the brain, leading to uncoordinated movement or ataxia.
Cat Limping May Indicate a Veterinary Emergency

If your cat`s leg is hanging at an awkward angle and they cannot and will not walk on it, or if there is an open wound, bleeding, or if your cat has been limping for more than 24 hours, it could be a veterinary emergency.

The signs of Horner`s syndrome in cats include changes to the way eyes look and function, such as: Upper eyelid droops. The muscles around your cat`s eyes will relax, and their eyelid will look droopy, as if the eye is half-closed. The cat may not blink with that eye, or blinking movement may be slow.
Occasional head shaking is perfectly normal but if your cat suddenly starts shaking their head a lot more than usual it`s likely to indicate a problem such as: Ear infection. Aural haematoma. Ear mites.
There is no treatment for Ehlers-danlos syndrome in animals. Severely affected kittens usually do not survive, but cats with mild or moderate forms generally live a normal lifespan, but are at risk of frequent skin tears and injury due to skin fragility and joint laxity.
Cats that are ill will usually show changes in overall appearance, energy level, sociability, coat appearance and/or amount of shedding, appetite, litterbox usage, breathing, or discharges from the eyes or nose. In general, any sudden change should alert you that your cat needs veterinary attention.
Head tilt is a medical condition that may be indicative of a serious underlying disorder, usually of the vestibular system. If a cat is tilting its head frequently to either side of the body (away from its orientation with the trunk and limbs), this is an indication that the cat feels imbalanced.
What is Feline Distemper? Also known as FPV and Feline Panleukopenia, Feline Distemper is a highly contagious viral disease that can be debilitating and even fatal. Kittens aged between 2 and 6 months are the most vulnerable to the disease, followed by pregnant and immune-compromised cats.
They tend to have certain physical characteristics like low muscle tone, short stature and a flat nasal bridge, and will also exhibit some degree of learning difficulty. Cats have only 19 pairs of chromosomes, meaning that it is technically impossible for Down syndrome cats to exist.

Q. Found kitten that seems confused shakes head and walks in circles what could be wrong?
ANSWER : A. It could be that he has suffered a head injury, or that he has a congenital problem or that he is intoxicated, or perhaps that he has a deep ear infection. The symptoms you describe are neurological, and potentially there are several possible causes that carry different prognosis. I have seen kittens with head trauma improving with the symptoms you describe, but pain relief is really important to be provided. I would suggest to have the kitten checked over.

Q. We brought 2 new kittens home. One of them is sneezing. We have a Sr cat and an adult who is now coughing. What to do?
ANSWER : A. Commonly respiratory infections (viral -Herpesvirus and Calicivirus- and possibly bacterial) can cause sneezing episodes in kitten especially if not vaccinated yet. If your kitten is affected by respiratory infection could develop or have more signs such as discharge from eyes, more discharge from nose, coughing, being lethargic, depressed and inappetent.

The coughing episodes of the adult cat could be completely unrelated to the cause of sneezing of your new kitten, especially if your adult cat is already vaccinated.

The cause of cough in adult cats are not necessarily related to respiratory problems, heart problems could cause that as well.

Keep the nose and the eyes of your kitten free from discharge, keep your kitten warm and take both of them to your veterinarian as soon as possible to identify the cause and the relationship of the two problems and treat appropriately.

Q. How do I teach my dog to sit still enough and not move his head while I clip on the gentle leader?
ANSWER : A. Most dogs HATE the gentle leader, and it’s not at all surprising. Would you want something foreign on your face? It’s an uncomfortable training tool, and no dog enjoys wearing it. If you are looking to have your dog behave better on-leash, you should consider tossing out that gentle leader, and using a front hooking harness like the Sensible http://www.softouchconcepts.com/index.php/product-53/sense-ible-harness, or the Sensation http://www.softouchconcepts.com/index.php/product-53/sense-ation-harness harness. These harnesses will eliminate the pulling power of your dog, and put you in control in a positive, and gentle way. Any time your dog pulls, he is redirected until he is facing you. You can practically walk your dog with your pinky.

I dislike the gentle leader because it can cause neck injuries in an avid puller/lunger. You also can’t ever hook a long-lead to the gentle leader and allow your dog to run around because it would break his neck. Another thing I dislike about it, is it discourages sniffing the ground during walks. When your dog attempts to sniff, and the leash is short, his nose is redirected upwards. When you trip on the leash, the head is jerked around and the nose is directed upwards. Sniffing during walks is extremely important. Sniffing = mental stimulation, which will tire your dog out more during your walks. The more your dog lags, or forges, the less he can sniff the ground, and the more frustrated he becomes.

If you’re dead set on using the head halti.. you should be using treats to hold his attention. Place the head halti on the floor, reward him for sniffing it, pick it up, treat him, put it near his face, treat him, lure his nose through the loop, lots of treats, take the head halti off, more treats, lure his nose through again, more treats. Take baby steps going forwards AND backwards so the “game” of getting the halti on isn’t always getting more difficult.

Q. My dog has had dark red blood in stools for 2 days now . She found & ate a baby bird back in August , could that cause a problem now after so long
ANSWER : A. It seems pretty unlikely to me that the bird ingestion could have anything to do with the blood in the stool you’re seeing now. Depending on exactly how it looks, it could be a number of things. If the stool is normal and has blood on it, it could be an anal gland problem (infection, tumor) or a problem inside the rectum, like a mass. If she’s got diarrhea along with blood, she could have a bacterial or parasitic infection in her intestines, or she could have inflammatory bowel disease. I’d get this checked out as soon as possible.

Q. I have a 1yr old male 38 lb Labradoodle and my gf just brought a month old kitten home. Can they interact? If not, for how long?
ANSWER : A. Interactions whenever a new pet is brought into the house should start off slow, then can be increased in time. The best steps when introducing a new cat is to allow your cat or kitten to have a room in the house all to him or herself. Allow your dog to sniff under the door to get used to the kitten’s scent, and even show your dog articles such as bedding the cat has slept on. After a few days, an introduction with your dog on leash, or a barrier such as a gate where both pets can look at each other but not see each other is best. This will allow each to get used to seeing the other without the ability to jump, bite or scratch the other. Once the two are used to this, then a face to face interaction can begin. If at any time a fight or scuffle breaks out, separate the two pets and try again at a later time. The amount of time this introduction takes can vary depending on how the two react to each other.

Until your kitten is older, or you are sure both are fine together, do not leave the two pets together unattended. Even a well-meaning and playful dog can accidentally break a leg of a kitten or worse without meaning to! A safe room for your kitten to be in while you are away, or a barrier to allow your kitten to escape to safety if needed will help until both are big enough to play alone safely.

Q. i believe my cat is pregnant but showing signs of being in heat
ANSWER : A. Cats are induced ovulators, meaning they will continue to go into heat until they are bred, or spayed (reproductive organs removed). If your cat is showing signs of being in heat (excessive yowling, presenting her rear to you for inspection, attempting to get out or other cats hanging near your house) and you don’t want kittens, it is best to have her spayed. Most cats are also semi-seasonal in their heat cycle meaning they will more likely be in heat through Spring-Summer than in Fall-Winter.

Pregnancy in cats lasts about 60 days. Signs of pregnancy may include weight gain, increased appetite, nipples that become pronounced or “leak” and seeking nesting areas to deliver kittens. If you saw that your cat was in heat, or had her mated, you can use the date she was bred to determine when she may be due for kittens. Your local vet can help determine if she is indeed pregnant and can also take an X-ray to determine the number of kittens present if your cat is nearing her due date. Be sure to feed mom a kitten formula in the last few weeks of her pregnancy and during nursing as it will help provide extra beneficial nutrients for both mom and babies.

If you do not want kittens, some very early term pregnancies can be aborted with spaying, otherwise spaying mom is usually done when kittens are weaned from their mom.

Q. I recently added a new 2 month old female kitten to my house and my male 5 month the old kitten has turned aggressive and chases the kitten down..
ANSWER : A. It is possible it could be play behavior but without seeing it in person, hard to say. Is the male kitten neutered? You may want to consider doing so. Also, try re-introducing the kittens slowly by creating a safe space for the new kitten behind a closed door in a room. Keep her there for at least a week so she is protected but your male is still able to smell her. After a week or 2, you can then graduate to using a baby gate so they can then not only smell each other but safely see each other as well. If that is going okay, after another few days you can bring the gate down. Also, be sure to have feeding bowls in separate locations and at least 2 litter boxes.
