Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Chimpu! Sadly I can't give you a prognosis with out a diagnosis and we can't do that over the internet. Chimpu needs to see a Vet for an exam, blood work and X-rays. Cats shouldn't go longer than 2 days with out eating as that can cause a secondary serious liver problem (fatty liver syndrome). Causes of a fever in cats are: viral or bacterial infections, feline infectious peritonitis, feline leukemia, pancreatitis, blockage from a foreign body and cancer. I do think this is serious since it has been 4 days. He should be hospitalized if possible until we find out the cause of his fever. I am not in full agreement that he won't survive, but I am worried he won't with out intervention. I wish you and Chimpu the best!

    These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). An infection is more likely given the higher temperature. A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed. Semisolid/liquid food can be supply through a syringe (without needle). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

    Chimpu is experiencing very general symptoms of disease, these symptoms could fit almost any internal condition, maybe he is suffering from nausea due to a gastrointestinal disease and maybe he is in pain, from the symptoms described it's very hard to know. i would recommend taking him to the vet urgently in order to get him checked, if he doesn't show any other obvious symptoms during the examination, a blood test and possibly an ultrasound will be needed in order to try and find out what is wrong with him.
