I took little Oli Dude back to the vet today, as I cannot get him to stop barfing. I stopped giving him his antibiotic because he would just barf it up 20 minutes later. However, very unlike himself, he also barfs at 230 or 3 am every night like clock work. So anyways, took him to the vet, and they gave him a shot to help keep the barfing at bay for about 36-48 hours. The vet thinks he is still enduring some sensitivity from all of the meds he had during his dental. So I guess time will tell.
But I would really really like to stop cleaning up cat barf.
