TL;DR: Jasper has only eaten approx. 140 calories in the past 7+ days and is still refusing to eat except for licking/eating a tiny bit of plain tuna. Is it time to have a feeding tube installed? My FD kitty, Jasper (and I), have been through the ringer this past week. I'll try to keep this short as I can. Jasper was diagnosed with FD and put on Prozinc in early Nov 2017. I was able to get him into remission with no carb food by mid Dec. In early Feb, he was diagnosed with hypertrophic cardiomyopathy, which is at an early stage so he needs no meds yet. His currently problems all started a week ago Wednesday. Following a bath for allergies (he usually tolerates these reasonably well for a cat), I noticed him breathing really hard and wheezing harshly. I rushed him into the emergency vet clinic and they diagnosed him pulmonary edema. He was immediately put in an oxygen cage and on lasix to get the fluid out of his lungs. Two days later, I took him up to a university small animal teaching hospital for a follow-up on his heart condition. Well, they inform me that he was misdiagnosed due to the xrays done at the emergency clinic being underexposed. They said he had a severe asthma attack, did not have fluid in the lungs and that I should immediately take him off of the lasix. Jasper has had asthma for many years, but I have never seen him any sort of attack like this so I didn't recognize it as related to his asthma. I was able to take him home that night, which was Friday night. He would not eat while at the hospital and wasn't interested when he got home. After a while I have him 1/8 tab of mirtazapine I had left over and I was happy when he ate a little wet food later that night. The next day, Saturday, he ate some more wet food and I thought he was doing okay, but later that night he refused to eat again and he did not look/act very well at all. I ended up trying to syringe feed him a little bit, but it didn't go well and he eventually vomited some of it back up. So Sunday, we took him back up to the emergency clinic at the university. They held him overnight and ran a bunch of tests on him including blood work, urinalysis, repeat xrays and an abdominal ultrasound but they didn't show much wrong with him other than they think he has a little bit of pneumonia in one of his lungs and they put him on antibiotics. He was also very dehydrated and had low potassium due to the lasix he was erroneously put on, so they addressed those issues as well. I took him back home on Monday. Jasper still wouldn't eat at the hospital and now he won't eat at home either. I have tried many things to get him to eat: heating up his food, offering a variety of foods including his dry food, all his favorite wet foods, new wet foods and plain tuna with juice. He doesn't like treats. I gave him another mirtazapine pill, which did nothing. The only thing he would respond to was the plain tuna. He licked it a couple of times, ate a flake or two and then abruptly walked away and hid under the bed. I thought that perhaps he was nauseous so I quick took him over to my regular vet. It was after hours, but she gave him a quick check and gave him a shot of Cerenia. We are back home now and the only thing that interested him tonight was the plain tuna again. He perhaps ate 1/2 tsp of it before refusing any more. I tried sprinkling some of it on his wet food, but he is getting irritated with me trying to get him to eat. Also, I have tried fortaflora and parmesan cheese sprinkled on top in the past and he does not care for either. I have been monitoring him for ketones throughout this ordeal and also had them run a Spec fPL test to try to rule out pancreatitis, but we don't have the results back on that test yet (vet thinks it will be negative based on ultrasound). His blood glucose has stayed fairly normal for his situation. It was in the 180's on my meter when he was the most stressed out and was at 107 this morning. Jasper has only eaten approximately 140 calories in the past 7+ days and of course the very big concern is that he may develop hepatic lipidosis soon. I have been in contact with the vets at the university animal clinic and they have advised that if he hasn't started eating by tomorrow, to bring him in to get a esophageal feeding tube put in. Jasper has been acting very ill and hiding a lot, but I have noticed that he may be feeling just a little bit better today with the tuna licking and he has been moving around/snuggling with me a tad bit more. Do you think it is time for a feeding tube to be installed, even though he licked/ate a tiny bit of tuna today? I am leaning towards yes. I would hate for him to go through all that and to then start eating right away, but every day, I fear his liver will become damaged. Very sorry for the extremely long post.
