Vitamin D toxicity, also known as hypervitaminosis D, can occur when a cat consumes too much vitamin D. This can be caused by accidental ingestion of vitamin D supplements, or by a diet that is excessively high in vitamin D.
Symptoms of vitamin D toxicity in cats may include:
* Increased thirst and urination
* Vomiting
* Loss of appetite
* Weakness and lethargy
* Weight loss
* Constipation or diarrhea
* Abnormal heart rhythms
* Calcium deposits in the kidneys
If left untreated, vitamin D toxicity can lead to serious health problems, including kidney damage and calcification of the soft tissues. In severe cases, it can be life-threatening.
It is important to always follow the dosage instructions provided by your veterinarian when giving your cat a vitamin D supplement, and to be careful not to give your cat any medications or supplements that contain vitamin D unless specifically directed by a veterinarian. If you suspect that your cat may have ingested a large amount of vitamin D, seek veterinary care immediately.
