Why is my newborn kitten not eating, shaking, and breathing heavily?

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.

Lea is quite young and it's very serious she is not eating. She cannot survive long without eating. Her symptoms tell me she is very sick and if she doesn't get veterinary attention now, she could die. Please take her into a vet immediately.

I would worry that Charlie has an upper respiratory infection. Viral disease is most common, and a secondary bacterial infection could occur as well. I’d recommend having Charlie examined by your veterinarian. If you think he is having enough difficulty breathing that he is in distress you should see an emergency veterinarian.

Thank you for submitting your question regarding your kitten. He sounds very sick. I recommend that he sees a veterinarian right away. In the meantime, you can place karo syrup or maple syrup on his gums in case he has low blood sugar. I hope this information helps!

The symptom you are describing are very concerning and Titan might be in great danger. He needs immediate vet attention. While you are traveling to the vet keep him warm (wrap him in a blanket). Good luck. Please post again on the forum if you would like to discuss it further. I hope my answer was helpful.

I wonder if maybe she has neurologic damage or did not heal after the panleukopenia. I would talk to your vet about blood work, a neurologic exam, and maybe referral to a specialist in internal medicine or neurology to determine what could be causing the shaking and loss of balance. Increased respiratory rate or changes in breathing sounds could indicate an upper respiratory infection, a nasal polyp, or possible scar tissue from previous infection.

If you are completely unable to feed him and it has been 24 hours since he has eaten, I would seek emergency care ASAP. There may be a functional issue or deformity that is preventing him from being able to eat properly which may need surgical correction or IV fluids/feeding tubes to bypass so he can get the nutrition he needs. Please try to seek care immediately at your vet or a local ER clinic, especially if he cannot eat at all or seems in distress.
