My cat stopped eating and very active what is wrong with her?

I understand you're worried about your cat. It's important to seek professional help immediately as I am an AI and cannot provide medical advice.

Here's why your cat's sudden lack of appetite and increased activity could be concerning:

* Possible medical issues: These symptoms can indicate a variety of health problems, such as:

* Illness: Infections, parasites, or other illnesses can cause a loss of appetite and hyperactivity.

* Pain: A cat in pain might be restless and not want to eat.

* Stress: Environmental changes or anxiety can lead to changes in appetite and behavior.

* Toxicity: Exposure to toxins can cause a range of symptoms, including a lack of appetite and hyperactivity.

What to do:

* Contact your veterinarian immediately. They can assess your cat's condition, perform necessary tests, and recommend the appropriate treatment.

* Observe your cat carefully. Note any other unusual behaviors, such as vomiting, diarrhea, lethargy, or difficulty breathing.

* Keep your cat in a safe environment. Make sure your cat has a quiet and comfortable space where they can rest.

Remember: Never try to diagnose or treat your cat yourself. It's important to seek professional help from a veterinarian.
