What is Stupor and Coma?

There’s a big difference between a deep sleep and a complete loss of consciousness. If you notice your cat losing consciousness, take him to a veterinarian right away, even if he recovers after a few minutes. The underlying health condition could be life-threatening, so it’s important to seek immediate medical attention to protect your cat.

At any time, cats are in one of five levels of consciousness, including normal, depressed, disoriented, stupor, and comatose. Although depressed states can result from minor illnesses, and disoriented states may be a sign of Alzheimer’s disease or dementia, stupor and coma states are much more serious. A stupor is characterized by a temporary loss of consciousness that can be disrupted when the cat is exposed to strong stimuli, while a coma is a more long-term form of unconsciousness in which the cat does not respond to any type of stimuli. Both of these conditions indicate there is an underlying health condition that needs immediate treatment.

Symptoms of Stupor and Coma in Cats

A coma is the complete loss of consciousness, while a stupor is a decreased level of consciousness. If your cat is in a coma, he will be completely unconscious and unresponsive to sounds or touch. In a stupor, your cat may be slightly responsive to sound or touch, however, the stimulus must be strong, such as a hard pinch. Stupors are temporary, so your cat may snap out of it after a short period of time, while comas are long-lasting. Besides loss of consciousness, some other symptoms you may observe include:

  • Low body temperature
  • Breathing abnormalities
  • Heartbeat abnormalities
  • Nervous system abnormalities
  • Discoloration of the skin

Causes of Stupor and Coma in Cats

Falling into a stupor or coma signals an underlying health condition that needs to be addressed by a veterinarian immediately. Some of the causes your vet may need to test for include:

  • Head trauma
  • Seizures
  • Heart failure
  • Kidney failure
  • Reaction to drugs
  • Poisoning
  • Hypoglycemia
  • Hydrocephalus
  • Brain infections
  • Side effects of diabetes
  • Brain tumors
  • Low blood pressure
  • Abnormal levels of sodium in the blood

Diagnosis of Stupor and Coma in Cats

You should bring your cat to a veterinarian the moment you begin to notice him losing consciousness. Tell your vet when the cat began to lose consciousness, and any other symptoms you may have observed. If your cat is fading in and out of consciousness in a stupor, try to estimate how long each incident lasts and how many times he has been unconscious. If your cat has recently started taking any new medications or using new products, mention this to the doctor so he knows whether it could be a reaction to something the cat has been exposed to. It’s also important to tell the doctor if it’s possible your cat has consumed something toxic—for example, if he had access to an open bottle of household cleaner.

The vet will first determine what state of consciousness the cat is in: normal, depressed, disoriented, stupor, or comatose. Normal means the cat is not experiencing any issues, while depressed means the cat prefers to sleep, but is still responsive. A disoriented state is characterized by excessive sleeping with abnormal responses to stimuli. Cats in a stupor only respond to strong stimuli, while cats in a coma do not respond to any form of stimuli. 

Once the level of consciousness has been determined, the vet will most likely test the cat’s reflexes. The vet will look at the pupillary light reflex by shining a light into each of the cat’s eyes and observing the reaction of the pupil. Other reflexes that may be tested include the spinal reflexes and oculocephalic reflexes.

The vet may then suggest a complete blood count, urinalysis, and biochemistry profile to see the cat’s overall health. The results of these tests could show if the cat is suffering from an infection, organ failure, or sodium or blood sugar imbalance. In addition to these tests, the vet may perform a CT scan or MRI on the head to look for signs of trauma or tumors. An EKG may also be done to check the cat’s heart health.

All of these tests will help the doctor determine what is causing the stupor or coma so it can be properly treated.

Treatment of Stupor and Coma in Cats

Treatment will depend on the cause of the stupor or coma. Short-term treatment to stabilize the cat’s consciousness may include inserting an IV with fluids, monitoring the cat’s heart rate closely, and supporting the cat with a ventilator that provides a constant stream of oxygen.

After the cat has been stabilized with this short-term care, the treatment will focus on resolving the underlying health condition. If the loss of consciousness was a result of some sort of imbalance, such as low blood sugar or sodium, the vet may be able to resolve the issue with the IV fluids. Seizures will need to be treated with anticonvulsant medication, which can be given to the cat in the vet’s office, but will then need to be administered on a daily basis by the cat’s owner afterward. 

If the vet believes the cat has ingested a drug or toxic substance, activated charcoal may be administered. Charcoal will enter the cat’s system and begin to absorb the chemicals before they make it into the bloodstream to do more harm. The vet may also induce vomiting to remove the toxic substance or harmful drug from the cat’s body. 

Some causes, such as head trauma, brain tumors, and heart failure may be untreatable. If the vet suspects head trauma is the cause, the cat’s head will be elevated at a 20-degree angle to prevent fluids from building up in the brain. Surgery may be able to treat these causes, but the success rate will vary, so it’s important to speak with your veterinarian to learn more before you make a decision.

Recovery of Stupor and Coma in Cats

The time it takes for your cat to recover will depend on the cause of the stupor or coma. The vet will most likely ask that you leave the cat with them so they can continue to monitor his vital signs and help him regain consciousness. While under the vet’s care, the cat will be hooked up to ventilators, IVs, and feeding tubes to ensure he is properly taken care of. The cat may regain consciousness while under the vet’s care, but that doesn’t mean he will be released to you right away. Vets will usually continue to monitor the cat’s vital signs until they are confident the cat has fully recovered.

Once your cat is back home with you, it’s important to administer medication as advised by the veterinarian. Make sure the cat is comfortable in your home while he continues to regain his strength. If you have other pets, keep them away from the cat until the vet says it’s ok for them to interact again. The vet may advise you to move the cat’s water and food bowls closer to limit the cat’s activity. 

You will need to keep a close eye on your cat so you can monitor his behavior and call a veterinarian if you notice anything unusual.

Seizures, Coma

Our 10 month old male cat was diagnosed with FI P on Tuesday. He already had some balance use issues but he was still eating, drinking,peeing,pooping. He was wobbly but running, jumping.The vet gave him prednisone and an antibiotic and said maybe this will give him a little help as far as pain,etc. But there is nothing more that can be done. This was his second trip to get vet in less than 2 weeks. 1st time they said he was anemic and had conjunctivitis but didn't see anything wrong and didn't see anything wrong with his walking. After he had a seizure on Wednesday we carried him back and got the dry fip diagnosis. After his first dose of prednisone the seizures got worse. Supposed to take it every 12 hrs. Beginning at 230a.m. On the 19th until mid night Stash had 16 seizures. Didn't give him any med on the 20 th seizures dropped in intensity and plenty to 11that day. He was walking better, eating,etc with the meds but I did call get to see if we couldn't give him something for the seizures because we know he's terminal. Was basically told no. Friday I think he went into a coma. Seizing every 30minutes to an hour( after restating prednisone), limp, eyes put unresponsive to anything. Only sounds made are at the end of the seizures which are not as intense or long. We've been using an eyelash solutions to keep his eyes from crying out, giving him water with a dropper, and giving him a high caloric suplement. By midnight last night by started moving his eyes a little, a little more responsive to touch and will close his right eye. He has had fevers, and we have had to really look to see if he was breathing. How is this little guy still alive? I know that he is aware of me sometimes because after he settled after a seizure,he reached with his law until I hold it. He would do this before he got sick. I'm pretty sure there is brain damage. Sometime his eyes are dilated at different sizes of one is and the other isnt. I'm not looking for a miracle cure. I've had cats with fi P before but they had set fip. 1st time to see dry. Can we do something for the seizures? I know euthanasia would be kinder, but he is still fighting, otherwise he would be gone besides my husband doesn't want to because he sees it as giving up. He doesn't want him to die in a place he's terrified of. What now?

Eye Bleeding

My cat had an eye surgery and during the surgery he reacted to porpofol anesthesia and died after cpr he went into a coma at first he used to react to touch but now he does not react and he cannot breathe on his own and then a few hours later he started twitching and having seizures. The seizures are gone now it is the second day he is unconscious but still cant breathe on his own and does not react to anything. His eyes are open but they twitch a bit. Mind you a couple of years ago he had a surgery and a dif vet did anesthesia and the cat did not react to it at all he was fine. Why did this happen now and what are the chances that he will come out of it and regain consciousness? Help

It does not sound like Chancy is having any quality of life, and letting her continue to live like that does not seem very kind. It would probably be best to have a veterinarian look at her and determine if there is any possible treatment for her.

Deep Sleep

For the second time now I’ve noticed that Mt cat goes into a very deep sleep and he does not wake up easily. Lifting his paw or head did and light petting did not wake him but a shake and loud talking did. When he woke up he seemed annoyed that he wasn’t being woken up. Ive read online that this happens to a lot of people’s cats. Is this normal or a sign of something more serious?

If Koda seems normal otherwise when he is awake and sleeps deeply, it may be normal for him. If he is lethargic and not normal once you wake him up, he may be ill. If you are not sure, it is always safest to have him examined by a veterinarian to make sure that he is healthy.

Without knowing what is causing the dehydration for Joselito, I don't have any way to know how long it will take him to recover, but if he is being kept in the hospital on IV fluids, that is probably the best place for him. Animals sleep when they are recovering, and you can ask your veterinarian more about whether he is recovering, as they can see him.

Comatose

My 16 year old cat was headed to Paris with me but over the last 6 months she had started showing her age. She started dedicating and peeing outside her litter box, stopped eating as much, and just seemed low energy and not very happy. I took her to the vet to get an opinion and he gave her an IV of fluid and an antibiotic. I brought her home and took a nap. Upon awakening, she was totally unresponsive and limp with her fear twitching a bit. I rushed her to the vet and he said she was comatose. I decided to say goodbye to her and she was euthanized. I have been going through all of the stages and questions. Did the antibiotic make her comatose? Should I have incubated her? I loved her but friends and family all had been nicely telling me that she just looked like she was on her last legs. Miss her.

Renal Failure

We sadly had to put my 18 year old little girl cat to sleep on monday. It's still so hard I raised her from a tiny kitten and she was my bestie. She had been having hyperthryroid problems treated with meds for the last year and a half. She enjoyed good health other than being underweight. I noticed her cheeks looking shallow sunday night and by monday afternoon she looked absolutely awful and we rushed her to the ER where the dr said she was in liver/renal failure. We were putting her to sleep by 7pm that same day. My question is, her eyes were open (but not moving) when we were saying goodbye but she wasn't moving her boy at all, shallow breathing, ears not moving, like a total coma. Do you think she could hear us saying our goodbyes? How could she get like this so suddenly in less than 6 hrs from being okay? Do they add a sedative the IV drip she was on?

Lifeless , No Heartbeat

I brought my cat to vet to have a tumor removed on his right back leg and his teeth were cleaned as well while under anesthesia, the vet tech brought my cat out to me and he seem to be doing very well his eyes were dilated the way they should be and he was howling from the pain of the surgery then the doctor came out and said please return the cat he is not released for discharge , I asked why you were taking my cat back and he said the vet tech was going to discharge your cat with a low temperature of 98, They took my cat to the back room to recover from low temperature in body, THEN THE VET TECH BROUGHT MY CAT OUT TO ME 1 TO 2 HOURS LATER AND WHEN HE WAS HANDED OVER TO ME HE HAD NO HEARTBEAT HIS EYES WERE TOTALLY DILATED BLACK NO COLOR IN THEM WHATSOEVER, I TOLD THE VETERINARIAN HE EITHER HAD CARDIAC ARREST AND NO ONE WOULD DO ANYTHING FOR HIM AND I INSISTED HE WAS DEAD AND THEY TOLD ME I WAS CRAZY THEY WERE ACTUALLY GOING TO SEND ME HOME WITH MY CAT LIKE THIS. I think my cat went into cardiac arrest or had a reaction from to much reversible drugs to wake him up faster because they wanted to leave early, he went in for surgery at10:14 am and came out the first time around 1:30nthen they took him back like I said because his temperature was low and then I received my cat back Gavin round 2:30 and at that time he was dead no heart beat was lifeless and eyes were totally black and glossy no color of pupil could be seen. I am however setting up a necropsy due to the inappropriate cate for my cat. Please give me your thoughts. Also when my cat went in for surgery he was very healthy
