Common European cat, male, castrated, he doesn't leave home, 6 years and 3 months old, food intolerance or allergy (fed with dry food Royal Canin Hypoallergenic), weighs 6,7kg (now 6,1 kg ).Our cat vomits since Thursday evening. The vomit initially consisted in dry food and hairballs. Than he began to vomit liquid and bile 3 to 4 times a day. On Friday we visited the veterinarian and he did blood tests and an rx of the abdomen because he feared the cat could have ingested some foreign body. From the x rays he could only see that the intestine was contracted. Since that moment the cat was given a powerful antiemetic and the vet asked us to force feeding him during the weekend. During the weekend the cat became apathetic, refused to eat and to drink. Sunday afternoon he began to lose liquid drops from the mouth and his left nostril. He started to show a strange behaviour (like he was chewing something while bending his head to the side). On Monday morning he vomited both at home and in the carrier. The vet administered fluids and electrolytes intravenously. He made another rx and antiemetic treatment+antibiotics in case he had some infection. The blood tests showed nothing to worry about. The RX showed a thickening of the esophagus wall. The cat continued to vomit as soon as we took him home. He vomited several times at night (liquid and saliva in large quantities). We forced feed him with the syringe but after a little he started vomiting continuing to drip from nose and mouth. Tuesday morning the vet decides to keep him in the clinic and to give him Plasil and a pro kinetic drug. The vet administered fluids and electrolytes. Than an ultrasound was done. The ultrasound showed an abnormality in one of the kidneys and an enlarged spleen and most of all a complete absence of movement in the stomach, colon and intestines. The vet reported that despite the antiemetic and the antibiotic the cat keeps vomiting.Later he was given Cerenia and a different pro-kinetic drug and the vet was expecting the cat to produce feces by morning (the cat hasn't evacuated since Saturday morning). The vet suspects that there is something mechanical that stimulates the pharynx and causes the act of vomit or something in the rhinopharyngeal apparatus and suggested making an endoscopy, given the nasal discharge which was becoming viscous. The cat kept moving the head to the side during nausea while similarly "chewing". The spleen was slightly increased in dimensions but the vet said it is excessive to say that this is the cause of the symptomatology.With the endoscopy the vet found a complete absence of movement in the intestines,stomach and colon. The three different pro-kinetic drugs still have no effect at all. Small enlargement of the kidney is considered accidental and the cat has no renal insufficiency, no pancreatic insufficiency, no hepatic inflammation. The nostril was cleaned during endoscopy and it is assumed that the nasal discharge is due to a reflux in the nose.He keeps producing a lot of saliva, than he swallows, and vomits because the stomach isn’t able to react and let the fluid in. The stomach is still full of bile and may be the reason for the vomiting. The vet has also emptied the colon manually because the whole intestine is still. The cause is unknown. As of today the cat keeps throwing up everything. He is still given the Plasil and pro-kinetic drugs without improvements. The vet now thinks the only way to start a movement again in the intestines is by surgery and manual stimulation and massage of the organs to provoke a reaction, through an exploratory celiotomy. He is considering asking a neurologist to see if it could be a mass in the brain but the idea is that the cat in this case would show other symptoms. Has anyone ever had problems with the complete absence of movement and reaction in bowl, stomach and intestines and knows if the surgery has good effects? Are there any alternatives? Ways to stimulate the autonomic nervous system without open surgery?
