Cats twitch for several reasons, most commonly because they are dreaming while sleeping, which causes involuntary muscle movements. Twitching can also indicate other underlying issues, such as feline hyperesthesia syndrome (a condition causing sensitive skin and twitching), nutritional deficiencies like low vitamin B1 or calcium, low blood sugar, toxicity or poisoning, nervous system disorders (including epilepsy), kidney failure, skin conditions like fleas or mites, or injuries causing pain. Some twitching is normal behavior related to excitement, communication, or sensations like itchiness. However, if twitching is frequent, intense, or accompanied by other symptoms such as hair loss, pain, changes in behavior, or seizures, a veterinary examination is recommended to diagnose any potentially serious health problems.
Common Causes Explained
- Dreaming: Twitching during sleep is normal and harmless.
- Feline hyperesthesia syndrome: Causes twitching, intense licking, skin sensitivity, and behavioral changes.
- Nutritional deficiencies: Lack of vitamin B1 or calcium can cause muscle tremors.
- Low blood sugar: May cause twitching, especially in diabetic cats.
- Toxicity or poisoning: Ingesting harmful substances could lead to muscle twitching.
- Nervous system disorders: Including epilepsy, can cause muscle spasms and seizures.
- Kidney failure: Electrolyte imbalances in kidney disease may present as twitching.
- Skin conditions: Fleas, mites, or irritation cause scratching and twitching.
- Pain or Injury: Physical trauma might provoke twitching and discomfort.
When to Seek Veterinary Attention
If twitching is coupled with other symptoms like pain, hair loss, seizures, changes in appetite or activity, or if the twitching occurs during waking hours and seems excessive, it warrants a vet visit for proper diagnosis and treatment.
