My cat's back twitches sometimes. Is this normal or hyperesthesia?

Gentle twitches can occur during relaxation or even during sleep. As long as Mila is otherwise eating, drinking, and acting normally, there is likely no reason for concern. If anything changes with Mila's overall behavior or energy level, it is worth taking a trip to the vet. I hope that all goes well!

I wouldn't worry overly about the twitching when they are asleep as many animals make active movements when dreaming. Your cat is likely simply twitching its skin because it is excited. As long as it is healthy and not showing discomfort when toileting I wouldn't worry about it. If it is really concerning you I would go to the vet for peace of mind.

I wouldn't describe baby kittens as twitching. They may be a little jerky as they are learning to walk or practicing other fine motor skills. Maybe try reposting with what exact behavior you are seeing. I hope this helps and please feel free to post any additional questions.

Some cats can twitch their backs if their fur is overly sensitive to sensation. Most cats twitch their backs due to fleas so I recommend to treat her for fleas and use a good product such as Cheristan or Revolution. If the twitching stops, then you know it was fleas. Worms don't generally cause back twitching but they can cause GI upset if the numbers are high enough. Also, if she is not spayed yet, you need to get that done ASAP as cats will start cycling as early as 6 months old. I hope this is helpful and please post any additional questions.

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.

The skin twitching and running can be a sign of fleas or skin irritation, and occasionally cats will display an extreme version of this with feline hyperesthesia syndrome. The open mouth breathing is a little concerning - this is usually a sign of cardiac or respiratory disease although occasionally some cats will breathe with their mouths open when they are very excited. If you see any labored breathing or the open mouth breathing continues I’d recommend seeing an emergency veterinarian.

IT could be that Honey is having a normal reflex in that eye. Sometimes when people are sitting they can have small muscle twitches too. Also sometimes Honey might be using her whiskers to sense what is going on around her before she falls a sleep. I really would not be concerned about this behavior as long as she is eating and drinking normally. I hope that helps
