13 signs your cat is unhappy; never ignore them.

Here are 13 signs that your cat may be unhappy, which should not be ignored:

1. **Decreased Appetite:** If your cat suddenly loses interest in food, it could indicate stress or illness.

2. **Hiding:** Cats may hide more than usual when they're unhappy or stressed.

3. **Increased Aggression:** Uncharacteristic aggression towards people or other pets can signal distress.

4. **Excessive Grooming:** Over-grooming or compulsive licking may indicate anxiety.

5. **Litter Box Issues:** Avoiding the litter box or urinating/defecating outside of it can indicate stress or health problems.

6. **Changes in Sleeping Patterns:** Insomnia or excessive sleeping can both be signs of unhappiness.

7. **Vocalization Changes:** Increased meowing or unusual vocalizations can be a cry for help.

8. **Avoidance:** Cats may avoid interaction or physical contact when they're not feeling well emotionally.

9. **Lack of Playfulness:** A decrease in playfulness or interest in toys can indicate boredom or unhappiness.

10. **Destructive Behavior:** Scratching furniture or other destructive behaviors may occur due to stress or anxiety.

11. **Change in Body Language:** Tense posture, flattened ears, or a tucked tail can all indicate discomfort.

12. **Physical Symptoms:** Hair loss, skin problems, or weight loss/gain can be signs of underlying health or emotional issues.

13. **Withdrawal:** If your cat withdraws from social interactions or normal routines, it may be a sign of unhappiness.

It's essential to monitor your cat's behavior closely and consult with a veterinarian if you notice any of these signs persisting or worsening. Addressing the underlying cause promptly can help improve your cat's well-being and happiness.
