I'm really sorry to hear about your cat's condition. Cats, like humans, can show signs of distress and discomfort when they are seriously ill or in pain. However, it's important to understand that cats do not cry tears in the same way humans do.
When cats are in pain or feeling unwell, they may display various signs of distress, which can include loss of appetite, lethargy, hiding, vocalizing differently, or even showing changes in their facial expressions. Excessive tearing from their eyes can also be a sign of discomfort or irritation. However, this isn't the same as crying tears due to sadness or emotional distress, as humans do.
In your cat's situation, the loss of appetite and the tears from the eyes may indicate that he is experiencing discomfort or pain. It's essential to consult with a veterinarian to assess his condition and discuss the best course of action for his well-being. They can provide professional guidance and advice on how to make your cat as comfortable as possible during this difficult time.
Remember to offer your cat plenty of love, care, and support during this challenging period. If it becomes evident that his quality of life is declining, it might be necessary to make difficult decisions to prevent further suffering. But only a veterinarian can provide a proper evaluation of your cat's condition and offer the best advice based on their expertise and assessment.
