Luxor kept his food down for almost 24 hours. I think about 18-19 to be exact. Maybe even 20. We got up this morning and there was vomit on the linoleum (thank god). Luxor has been pooping, peeing, eating, drinking and even purring and playing. I'm thinking he probably doesn't have a blockage anymore but his tummy is still upset and he should be eating pretty bland stuff.
