Vomiting white foam can also be caused by illnesses of the digestive tract that need further treatment. Illnesses that can cause vomiting include hepatitis, pancreatitis, diabetes, and kidney disease. If the vomiting persists a few days, even with a bland diet, consult your veterinarian.
Bake the squash for 40-45 minutes. Bake it until it's tender. After 35 minutes, start poking it with a fork to check to see how tender it is. Then, remove the squash from the oven.
Bake about 350 degrees for 20 to 30 minutes. Then scrape the insides with a fork into a bowl. The bowl of squash will look like a bowl of yellow spaghetti. You can also use the microwave, but it will still take 20 to 30 minutes until it is soft enough to scrape.
