Do cats get morning sickness when pregnant?

Horses are unable to throw up. So, not that type of morning sickness. They can colic though, so just be sure they don't do that. If they do colic, keep them moving. Get some friends over & take shifts walking your house & give him plent of food/water. DON'T LET HIM LAY OR SIT. Take him to a vet if it doesn't improve by the next day. Signs of colicing is not eating or drinking, laying. Keep an eye on your house. If you ride them too much, they can colic, as well as if they get over-heated. Colicing is like a stomach ache & since horses can't throw up, it can become very serious.
