Cat ate fibrous white part of an orange
My cat is 11 years old and with the exception of 1 episode of FLUTD she has never been sick. Friday morning she began crying and vomiting a LOT, she threw up at least 15 times in an hour. I took her to the vet that day and she had an x-ray which didn't show anything unusual. The vet gave her an anti-nausea shot and some fluids, as she was pretty dehydrated from throwing up so much. She ate and drank normally once I brought her home, and didn't throw up at all yesterday (Saturday). This morning (Sunday) she threw up 3 times in my bed & has been quite lethargic all day. In one of the piles of vomit there were some white stingy things (which I did not see in any of the other vomit), so I looked at them closely and I'm 95% sure that it was a piece of the white fibrous part of the centre of an orange. Do I need to take her back to the vet, and if so can i wait until tomorrow (the only clinic open here on sunday is the emergency vet and i have no way to get her there)? Can she pass this on her own, or is this an emergency situation?
Please help, I don't want anything bad to happen to her, I'm really concerned
