My cat is quiet, not eating, losing weight, and breathing fast. What's wrong?

I believe these very general symptoms are very worrying, i cannot tell you what is the cause as there are many options but i strongly advise that you take him to the vet urgently to have a blood test done and get this checked.

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.

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.

You need to get Jax to your vet for an exam. He may have a viral disease like FIP that is causing his symptoms. This can be fatal. Please read this article for more information. http://www.peteducation.com/article.cfm?c=1+2134&aid=212 I strongly suggest you get Jax to your vet as soon as possible so a diagnosis can be established. That way Jax can get the appropriate treatment.

Thank you for submitting your question regarding your cat. If possible, you need to seek veterinary care for him immediately. He appears very sick in your pictures and your description. He will likely need blood work and x-rays of his chest to determine why he is so sick. In the meantime, place karo or maple syrup on his gums. This will help if his blood sugar has dropped too low. It will give him a little energy. He will still need care though. I hope this information helps.

I'm sorry to hear that Midnight is doing so poorly. As Dr. Darvishian mentioned, breathing changes are a medical emergency and should be addressed by an emergency vet right away. It's possible that Midnight's breathing changes, coughing, weight loss, weakness, appetite and drinking changes, and lethargy could be due to congestive heart failure, asthma, cancer, or many other issues. She's likely experiencing restlessness and a loss of appetite because she can't breathe well enough to comfortably lay down or swallow. I strongly recommend taking Midnight to an emergency vet right away. This is not a situation that can be managed at home. I hope that everything goes well.

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.
