Friend, the main concern is that the cherry pit can become obstructed. This is what you can do:
1- Do not give things like Pepto Bismol or Imodium. Start her on Pepcid AC (famotidine) 10mg 1/4 tablet every 12 hours for the next 2-3 days. You can buy Pepcid AC over the counter in any pharmacy.
2- No food or water for 3-4 hours. Need to give her gastrointestinal tract time to rest.
3- After 3-4 hours offer a small amount of water. Wait half hour, if no vomiting, offer a small amount of rice (50%) and boiled boneless chicken or ground beef (50%) 4-6 times a day. Keep her on this diet for several days then wean her into her regular diet. Make sure you check her stool to see if she passes the pit.
4- If she continues to vomit after doing the above she will need to be seen by your family veterinarian for a hands on examination. If she continues vomiting during fasting, lethargic, not willing to eat, pale gums, etc. have her checked by ER veterinarian.
