Hello,
I am so sorry to hear of your frustration over your cats case.
I am not able to give much advice on this case with specific details to treatment but I will add that I think seeing a feline practitioner (someone who just sees cats) and see if they can help.
I am sorry but I cannot advise a homeopathic vet on this case, it is too far advanced.
I wish you the best of luck
Hello,
If it truly happened overnight then it is most likely infection. If he is acting normally it may not need to be addressed today. But I do recommend it be seen asap. The longer infection sits the more difficult and dangerous it is.
