Sorry I'm just getting back to this forum....am in charge of fundraising at my daughter's school and September is a busy month - plus I got a job at the school and suddenly my available time to use my computer for personal reasons has all but disappeared.
The diahrrea did not resolve even though kitty was only on the food he had been weaned onto by the breeder (the kibble he got into was also what the breeder had him on), so we stopped all kibble and just stayed with his soft food. Diarreah and occasional vomiting (maybe once or twice during the week) still persisted for a week, so we did a PCR panel for uncommon parasites and everything else that could be suspect...the only thing that came up positive was corona virus. She said that the diahrreah was probably caused by him shedding the virus cells.....he still sneezes as well and for that he is taking L-Lysine twice a day...the sneezing is definitely slowing down. No discharge whatsoever from the sneezes and he is still as energetic as ever - and still growing like a weed.
The vet finally put kitty on Tylosin for 6 weeks and a GI diet and the diahrrea has slowed down and pretty much stopped, although the poop is still soft; the first part comes out soft and formed, the last part is usually drippy. He is also getting WAY too big for his litterbox, so the other day, he missed and pooped outside of this box, so I examined his stool...at the very end of the poop, there was a drop of red blood, although I did not see blood throughout the stool. He still has weeks to go on the Tylosin, but I now wonder if it might be time to xray or ultrasound to take a look inside. Perhaps he did swallow something that is irritating his bowel or maybe he has IBS????? He is still growing and 7 lbs now (3 lb gain since August 24th).
