I guess I spoke too soon. Couver was pacing last night and wanted outside. His tummy was gurgling and he had loose stools several times throughout the night. He also vomited up two small piles of liquid. I went to give him breakfast and he had no interest at first. He is eating now, but I can tell he's not feeling well.
I am going to call the vet today to determine the next steps we need to take. Maybe he needs some Cerenia to keep things down? I don't know... I will see what she has to say
