Hi and thanks for your post. Vitamin D3 is the more concerning item over the calcium. Vitamin D3 ingestion would cause a problem at 0.5-3mg/kg of body weight. He is 4kg and 800 IU is 0.02mg therefore 0.02/4kg=0.005mg/kg dosage which is below the 0.5mg/kg cut off and is likely not enough to cause a problem. I would watch him today and tomorrow and take him into your veterinarian if any signs of illness are noted: lethargy, vomiting, diarrhea, drinking a lot of water, not urinating or urinating more frequently. However if you are still concerned and it has been less than 2 hours since ingestion, you may take her into an emergency veterinarian to induce emissions (vomiting) and have her assessed. Best of luck to you and Chewbacca!
