My pet has the following symptoms:
We took Remi to the vet four days ago after a series of vomiting and bad diarrhea that occurred early that morning. We found him sleeping by the bathroom after discovering three random spots he vomited over the night. When at the vet, he refused to eat a treat offered to him (which he never refused in the past). Also, he made random adjustments to his posture during the examination - which the vet said was a sign of abdominal pain. After his temperature was taken (which was low) and a further rectal examination, he suddenly had bloody diarrhea. The vet took a couple of x-rays and a blood test. X-rays revealed nothing, except the vet noted his liver is quite small. The blood test showed low levels of protein; and, after further analysis, his albumin level was at 1.7 (he's 3.8 kg). The vet decided to hospitalize him to ensure he got enough fluids as well as to monitor him further. They gave him a shot/IV fluid to help w/ his nasuea. Additionally, they gave him half a pack of plasma transfusion to boost his albumin levels. Later that day, they did an ultrasound. The small intestines appeared oddly rippled and at the entrypoint they saw a black mass which they thought was a build up of excess fluids. After consulting with their team, they felt it was most likely Remi had consumed a foreign object and should undergo surgery. They told us of all possible outcomes and we agreed to the surgery. Post surgery, it turned out there was no foreign object. They "explored" the area and found nothing abnormal beyond a minor build up of plaque in the intestines which they took as a sample and sent for a biopsy. Otherwise, Remi came out of surgery as good as possible. Day 2 Hospitalization: Remi was very weak, tired and refused to eat. They gave him the remaining half pack of plasma post-op. There was no improvement in his albumin levels. He appeared in a lot of pain. Day 3 Hospitalization: Remi was weak, tired and continued to refuse to eat. He threw up again during the day. He received some synthetic protein. His albumin levels actually decreased to 1.1. His belly area appeared bloated - but the vets noted this can happen due to post-op/anesthesia and a build-up of fluids in the body. We walked him for the first time during our evening visit. He was slow, but walked. During our walk, his stool was liquidy/soft but and dark brown. Day 4 Hospitalization: During our morning visit, the vet mentioned that he may have an infection of the pancreas. He received another two doses of plasma to boost his albumin levels, which are now 1.4. He also had a chest x-ray to see if he had any fluids in his lungs - which there was none. He had more energy and walked with us during our evening visit at a rapid pace. He did not eat from us - even when lunch meat was offered (which the vet okayed). Again during our walk, his stool was soft but and dark brown but firmer this time. Could there be any other causes for what is happening w/ Remi? Are there questions that we should ask the vert that we've missed? What can we do after he is released from the hospital to ensure he maintains appropriate/healthy levels of albumin - What foods would you recommend? Thanks!
