this is the third day, at first we werent for sure if it was him or the dog
he seems to be vomiting every few hours, we have left food out for him and he appears to have attempted to eat some of it but we have not seen any food in his vomit today.
I wouldn't let this go for the entire weekend....he should be seen by the vet today if possible. The green vomitus is bile from an empty stomach. I'm concerned about the possibility of a blockage that is preventing food from passing through his digestive system.....he may have gotten hold of something and ate it, and that is blocking his gut, or he could have a growth or tumor blocking things......examination by a veterinarian is the only way to know for sure. If it was simply a virus or upset tummy, it wouldn't last this long and usually, they are able to keep down food when they do attempt to eat, at least portions of it. The fact that he is now vomiting up clear phlegm and bile leads me tp think there may be something more serious happening that should be investigated.
Please let me know what your vet finds or if I can help further.
