If there were bones and we have lip licking, drooling, and vomiting; this raises concerns of the bones being caught in the stomach or having irritated the stomach lining. In either case, we need to tread with care.
Now since you noted no belly discomfort or gum discoloration for him, we can try some supportive care to try to allay the nausea and encourage any bone material to pass. To start, we can try to reduce his nausea with an antacid. Common OTC pet safe options would be:
Pepcid (More Info/Dose @http://www.petplace.com/article/drug-library/library/over-the-counter/famotidine-pepcid), Zantac (More Info/Dose @ http://www.petplace.com/article/drug-library/library/over-the-counter/ranitidine-hcl-zantac), or Tagamet (More Info/Dose Here @ http://www.petplace.com/article/drug-library/library/over-the-counter/cimetidine-hcl-tagamet) Whichever you choose, we’d give this 20 minutes before offering food to allow absorption. Of course, do double check with your vet if he has a known health issues or is on any medications you haven't mentioned.
Now if he settles with the antacid, we can continue supportive care. Though if he cannot, then we'd need to think about having him seen since blockages and damage would become more of worry. Though if he can and because there is a concern that the bones are still in the stomach, we can start by feeding him a "Vaseline sandwich." This will sound odd but the aim here is that the bread will coat the any sharp bits and bulk up what is being passed in the gut. And that Vaseline will act as a lubricant to aid sliding this through the GI with hopefully minimal damage. To make this, you just want to spread Vaseline (or cat hairball treatment) over a piece of whole wheat bread, slather it on, and cover this with a second slice. This can then be hand fed to in pieces.
Afterwards, we will want to start him on small meals of bland food (ie cooked rice with boiled chicken/white fish or scrambled egg) for the next few days. Whichever you choose, you consider adding a spoonful of canned pumpkin to the meals. The fiber in the pumpkin will further encourage any material to move through the GI. As well, cat hairball treatment or a GI lubricant (ie Latulose, Miralax, food grade mineral oil) can also be added to these meals to help it slip through.
While encouraging passage of this bone material, you do want to keep a close eye on him. Specifically, we need to keep an eye out for any belly tenderness or pain when you press on his stomach, pale gums, straining to pass feces, passing blood in vomit or stools, appetite loss, restlessness, or black feces. If you did see any of these; then those are all red flags of a possible blockage or trauma and would require him to be seen urgently by your vet for an exam +/- xray.
Overall, we do always have to tread with care in situations like this. And I am concerned that the bones in this are to blame +/- a pancreatitis from the meat being fatty. Though in all causes, we’d want to use the above steps to settle his stomach, encourage this to pass while we keep a close eye on him. If we can do this for the next 48 hours and see no issue, then we'd suspect we are out of the woods. But any of those signs or if he keeps vomiting and we'd need to plan to have him checked by the local vet.
