If your cat suddenly eats less or more than usual, it could indicate an underlying health issue.


A lack of energy or increased sleepiness may be a sign that your cat isn't feeling well.

Weight Loss or Gain

Sudden changes in your cat's weight can be a red flag for various health concerns.

Vomiting or Diarrhea

Frequent vomiting or diarrhea could signal digestive problems or infections.

A cat that stops grooming or excessively grooms may have discomfort or pain.

Altered Grooming Habits

Changes in Litter Box Behavior

If your cat urinates more frequently or has difficulty using the litter box, it may indicate urinary issues.

Bad Breath

Foul-smelling breath can be a sign of dental problems or other health issues.

Coughing or Sneezing

Persistent coughing or sneezing may indicate respiratory issues or allergies.
