Okay so we have this cat whose probably upwards of 12-14, he could be older. We believe he has hyperthyroidism, but it hasn't been diagnosed. We are absolutely unable to get a vet because it is Thanksgiving tomorrow and none are open. He has been throwing up yellow-green vomit occasionally all day. I'm wondering if anyone has any advice for how to help him. All the information I can get online tells me to get a vet. Very helpful. I'm just looking for maybe some supportive care I can give him to help get him through this. I think he's probably throwing up bile. I read that actually feeding him might help to lower bile production, but he's not interested in eating anything. Should we try to force feed him? Any advice would be appreciated.
