My sweet Sabrina is an 11 year old Torti. For the past couple of years, she has experienced increasing episodes of vomiting and in the past 6 months, the vomiting has been projectile at times. Vet put her on prednisolone in February 2017 and put her on a new diet of Hills Science Prescription z/d dry kibble. She did well on the prednisolone but I was worried about her being on it long term so after her being on it for 8 months, tapered off and she went completely off it in November 2017. At that point, the vet wanted to try her on Pepcid AC to try to control the vomiting which gave her terrible diarrhea. She lost a lot of weight during November and December 2017 and started projectile vomiting. On January 2, 2018, I took her to the vet and he ran bloodwork and tried another short course of prednisolone, this time for only a month. He switched her diet to the Hills Science Prescription i/d. He also felt some impacted fecal matter when he examined her and sent us home with some lactulose and also prescribed metoclopramide as he thought it would help increase intestinal motility. From January - April of this year, she gained some of her weight back and would sometimes go as long as a week without vomiting. Then, 4 days ago, she had projectile vomiting in the middle of the night, followed by hiding the next day and when she came out, appeared very lethargic and walked like she was in pain. She then had more projectile vomiting that evening. She was not eating her dry food so I gave her some canned food. She went 2 1/2 days without a bowel movement and then finally went last night but was straining. I took her to a new vet today to try to get a 2nd opinion. Vet said it sounded like IBD and that she may need to go on another course of prednisolone and stay on it the rest of her life. The vet drew blood to run a digestive panel, gave her a shot of B 12 and also so IV fluids as she was very dehydrated. Vet also weighed her and said she is very underweight at only 5.5 pounds. When I asked about if diet could be contributing and was concerned that many of the prescription diets contain grains, the vet said Hills z/d diet or a duck and potato diet would be best. The vet also wanted to do an endoscopy to examine her small intestine and do some biopsies but the cost was going to be $1,200 which I can't afford. So the vet sent us home with the prednisolone and said I may also need to give regular shots of vitamin B 12 but she would wait until bloodwork came back to determine if that would be necessary. Has anyone out there had experience with IBD? If so, do you have any suggestions on diet? I honestly hate the prescription diets as they are just a multi billion dollar industry and I also read quite a bit on grains not being good for cats. Thank you for taking the time to read my lengthy post! I am so worried about my little girl.
