I force-fed my kitten goat milk formula today and it vomited at night
Vomiting after force-feeding goat milk formula may be gut irritation or stress, and underlying gut disease like bacterial enteritis, gastritis, parasites, or panleukopenia can also cause it.

My dog was excited before eating, then lethargic after, lies still, eats only a little meat, passed soft stool with faint blood, then whines, sits restlessly, and keeps pawing at its face
Based on the signs, the dog likely has an esophageal or gastrointestinal blockage from eating too fast or hard food like bones, causing throat pain and restlessness (hence pawing the face). If choking, use the Heimlich maneuver; it may also be allergy or acute gastritis, or parasites/parvovirus. See a vet for a full check.

Why does a cat foam at the mouth after eating fish or drinking milk?
Foaming after fish or milk may be food sensitivity or allergy, since cats cannot tolerate lactose in milk and some fish upset the stomach; it may also be food poisoning from toxic fish or dairy, or overfeeding causing acute gastritis. Stop these foods and see a vet if the cat is lethargic or keeps vomiting.
