Long term prognosis for recovery of your cat will vary from cause to cause. Infections and pneumonia are serious illnesses that need a high degree of specialized veterinary care. In all cases, your cat’s chances for a full recovery will increase if immediate veterinarian care is sought as soon as initial symptoms are detected. Additionally, given the seriousness of lung and breathing issues, you should follow up after symptoms in your cat have resolved in order to prevent potential recurrence.
These situations are difficult, but without examining Buddha I cannot start to say what could be going on with her especially with her older age; if she is stressed out by visiting the clinic you should see if you can get a call out or if another Veterinarian will make a house visit just to check her over. There are many possible issues which may be affecting an older cat, but an examination is required to narrow down on a diagnosis. Regards Dr Callum Turner DVM
Allergy medicine wouldn’t help here, it may be a case that the beef tendon is causing pain or an obstruction for Kingston which may explain his posture of sitting and his increased respiratory rate. I would keep an eye on him, but if there is no improvement within a few hours I would recommend taking him into your Veterinarian for an examination; I wouldn’t induce vomiting since if there is an obstruction this may cause more pain and distress for him.

There are various different causes for rapid breathing which may include infections, pain, heart disorders, dehydration among other causes; a cat’s respiration should be below 30 breaths per minute when at rest but if it is significantly above this rate at rest I would suggest visiting your Veterinarian for an examination to determine a cause.
