I have a girl who just turned 18. She has always been amazingly healthy. At 16 she had blood work and dr said only thing abnormal is now good it is for her age. Everything has been fine and she is eating and acting the same. Then one morning she ate breakfast then had diarrhea and went around the house bearing down and droplets came out. I took her to vet and no temp, weight actually had gone up a smidge from 2 1/2 years prior and no masses or things felt. We were given metronidazole and sent home. She took it and all was great. Then, on the 4th day after stopping meds, it happened again. I took her to urgent care and did a stool sample. Diagnosis of possible IBD bc she couldn’t figure it out. Cat is on metronidazole again and eating and acting normal. Took her to vet again today for further testing. They couldn’t draw much blood so they will try again tomorrow, but no weight loss and a more intensive feeling for masses showed nothing. He has no idea what is wrong. I’m so worried about her. She acts completely normal. Even when she had the diarrhea. She’s only had the diarrhea those two days. Normally her poop has been fine. Any help or what to ask for when I take her tomorrow morning? So nervous for sedation. Should I ask for ultrasound or X-ray?
