My cat is on the ground, twisting, and making weird noises. Is she okay?

Unfortunately, without a video, it is very hard to explain what Nancy may be doing. Kittens love playing and often rolling around on the floor is a very normal behavior. My cats do that all the time.

Cats will often roll onto their backs or sides and kick either in defense, or when playing with/attacking something. If he's grabbing onto something such as a toy or blanket while he does this, it could be what he is doing. If he is otherwise healthy and active, I wouldn't be too concerned by this behavior. However, if you see any signs of illness such as confusion, loss of balance, etc, in addition to it, it is always best to schedule a vet visit to rule out any health issues.

It is quite likely she is in heat, especially if she is also calling or shouting loudly. If you do not want kittens, be sure to keep her indoors and isolated from any unneutered male cats until you can have her spayed

Cats can have erratic behavior sometimes if they are playing or otherwise "wound up" however licking and chewing at the body during this behavior is not normal. Your cat may be exhibiting pain (especially with the muscle twitches and licking/chewing) and is trying to get your attention about this. Where he is licking can also indicate where the problem may be such as the back, legs or even urinary tract. (Urinary blockages are common in male cats and can present with symptoms such as excess vocalization, licking and chewing at the urethra/penis, attempting to urinate without success, or signs of severe distress and is a medical emergency). If your cat is presenting with these behaviors it may be a good idea to schedule an appointment with your local vet to make sure there is not an underlying pain or illness causing it.

This behavior sounds like a female cat in heat. If you would like to post some photos of the genital area we can help you determine the sex of the kitten appropriately. If is best to have her spayed as soon as possible if she is a female. https://www.petcoach.co/article/spaying-ovariohysterectomy-the-benefits-in-cats/ http://www.humanesocietymiami.org/low-cost-spay-and-neuter/ http://thecatnetwork.org/help-a-cat/spayneuter/meow-mobile/

It could be that your kitten is suffering from vestibular disease if she is moving around in a circle. Vestibular disease is a neurological disorder that can be caused by an ear infection, bacterial infection, inflammatory disease, or polyps among other causes. I would have your kitten seen by a vet immediately for this, who can diagnose the cause of her circling and can treat her.

Thanks for using Petco Pet Education Center, formerly Petcoach! This may or may not be abnormal or represent a condition that needs any sort of therapy as this may be a sign of discomfort. However, keep in mind that this may also be normal and just be something behavioral. If this continues, I recommend you have Maya evaluated by a veterinarian who can perform and examination and recommend accordingly. Good luck!
