My cat has seizures, drooling, and fast heart rate. Is this normal?

Mama Kitty sounds quite ill. Repeated abnormal neurological behaviors could be due to a seizure (which can raise the body temperature significantly to the point of causing brain swelling/damage), infectious diseases, toxins (although you report that this didn't occur), among others. Since she has such a high fever and is repeatedly having these abnormal behaviors, Mama Kitty should be examined by a vet immediately and will likely require hospitalization to monitor and attempt to resolve her high fever. I hope that she's on the mend soon!

She needs to be examned by a vet to determine the cause. It could have been a seizure but could also be caused by a heart problem, like cardiomyopathy. Your vet can do a workup to diagnose and then determine if treatment is needed.

This could be something serious like a seizure or a problem with his heart. Next time it happens, try to video the episode on your phone, and then take him into the vet. You can show the vet the video, and the vet can diagnose what is causing this so he can be treated. I hope this helps!

Odie needs to see a veterinarian ASAP!! This is obviously not normal. Seizures in cats are not a good sign. Based on the fact that he is so young my guess is that he may have ingested a toxin/poison of some sort or sustained some trauma. There is nothing I can tell you to do over the internet. You have to have a diagnosis before any treatment can be offered. This is serious so please get him to a vet as soon as you can. Best wishes.

I do not think it's related to killing those mice, Epilepsy in cats is not very common either, you will have to monitor her, if it happens again in the next couple weeks, you will need to take her to the vet in order to get it checked (full blood test).

I suggest taking your cat to your veterinarian or a 24-hour emergency clinic as soon as possible. Excessive drooling in a cat can be a sign of a number of problems including (but not limited to) nausea, dental disease. Ingestion of a toxin, foreign object caught in the mouth, salivary gland disease, ulcers in the mouth, cancer of the mouth, neurological disorders, or eating something that tastes very bad. Excessive drooling is also a symptom of rabies. Many cats will chatter their teeth while watching birds or other prey animals; however, chattering could alos be an indication of pain or neurological in nature.

I would be concerned that Crazy got into something toxic, or has a severe neurologic or muscular problem from the symptoms mentioned. It would be best to seek care from your vet or an emergency clinic right away.
