What would cause a cat to have heavy breathing and not eat lay around glossy eyes?

I'm sorry to hear your cat is not feeling well. As an AI, I am unable to provide medical advice. It's important to consult a veterinarian immediately.

The symptoms you're describing (heavy breathing, not eating, laying around, and glossy eyes) could indicate a serious health issue. Possible causes include:

* Respiratory problems: Infections, asthma, pneumonia, heart problems

* Gastrointestinal issues: Blockage, infection, poisoning

* Pain: Trauma, injury, illness

* Metabolic issues: Kidney disease, diabetes

Do not delay seeking veterinary care. Your cat's health is at stake. Please contact your veterinarian or an emergency animal clinic right away.
