Please know that coughing (unles it's a hairball) or panting is NOT ok in your cat. We had an upper resp, virus go through our house and 2 cats were fine. The 3rd I thought had mucus in his throat or trouble breathing due to stuffy nose like the rest and didn't realise his distress till he coughed up a frightening gob of green phlegm. Bob spent last night @ the vet w/pneumonia. happily (so far-say prayers for my boy) all signs looking good for him and he's coming home tonight. Had i known the coughing and panting were signs of distress I would have acted much sooner and I feel terrible for my cat's unnecessary and preventable suffering. If I can prevent this happening to one of your babies just by spreading a little knowledge, I'll be so glad. Good thoughts for Bob, please.
