My cat is breathing hard, not acting like himself, and not eating.

Poor Mochko. With symptoms of decreased appetite and "hard breathe" which I assume means she is having a hard time breathing, it is possible Mochka has pneumonia or an upper respiratory infection. I would highly recommend getting her seen by your vet again or another vet for a second opinion. They need to listen to her chest (auscultation) to check the lungs for certain sounds. If certain sounds in the chest are detected and Mochko also has a fever (greater than 102.5 degrees F rectal temp), then pneumonia is suspected. Chest x-rays would then be needed to confirm. If the chest is free of any abnormal sounds on expiration, then an upper respiratory infection is suspected, which is a better prognosis for kitty. At that time a short course of antibiotics and anti-viral meds (i.e. Lysine) can be prescribed to treat her condition. At any rate Mochko needs to be re-evaluated and the underlying condition properly identified so that we know exactly what she needs to get better.

This is a medical emergency - he is also very pale which indicates he is not getting sufficient oxygen around his system. This can be due to anemia, heart/lung disease or severe infection and shock. Please have him fully assessed by a vet urgently as this is immediately life threatening

What a gorgeous cat! I am sorry he is not feeling well. Licking his lips is a sign of nausea. Even though he may not be vomiting today he is showing signs that he is still not feeling well. If he is eating (even small amounts) and drinking water as well as interacting with you, urinating, and defecating than he may be able to wait until Wednesday. However, if Michaleto's breathing continues to be abnormal at all to you this may be a sign that he is in pain or has some sort of disease of his heart or lungs. Any abnormal breathing - whether fast or hard - should be seen as soon as possible by a veterinarian. I hope he is feeling better soon.

Oh dear! Poor Prince. I'm afraid these are very concerning symptoms. This does sound like a life-threatening problem, so I would recommend taking him to an emergency vet tonight to be seen. If this isn't possible, then he needs to see your regular veterinarian first thing in the morning. He will likely need blood work and x-rays to help diagnose the problem and see what can be done to help.

If the cat is struggling to breathe and not eating then sometging serious is likely going on. Unfortunately there is no simple solution for this, you will need to have tbe cat examined to determine the exact issue then allow for appropriate treatment. If you dont find a vet it may be a poor outcome.

Your cat sounds critically ill and should be seen by a vet ASAP. Open-mouth breathing is always an emergency in cats - it is a sign of respiratory distress. It is difficult to say what the cause is without doing some testing, but possibilities include cancer, pneumonia, asthma, or heart failure.

You are correct that Jeje's respiratory rate is higher than normal, but it's good that he's breathing with his mouth closed. I would be very concerned if he was opening mouth breathing, as that's a sign of respiratory distress in cats. He may not be feeling well at the moment leading to the increased respiratory rate. Because I can't see him in person, I can't say for certain he will be ok, so it's certainly fine to take him into a vet now for a health check. Otherwise, you can monitor him, and if his respiratory rate is still high in the morning, I would have him seen by a vet.
