Why does my Oriental Shorthair cat vomit her food? Most importantly how do I get her to stop?

She is eating too much too fast - normally that would be with dry food that is not good, overloaded with carbs and starches they do not need and cannot digest. Switch to wet food, do yourself a massive favour.for her benefit.

Siamese and the orientals are known to binge and barf. The food puffs in their stomachs too fast and they end up nauseous and puking as a result. On the plus side, one cat food company makes a food specifically for oriental breeds (and other cats with the same problem) to stop this. I've used it and it does GREATLY reduce the amount of barfing. Royal Canin Siamese 38, it's $12 a bag, and the bag lasts a whole month for one cat so that comes down to $3 a week, affordable. It's high protein too, and a pretty good food, our diabetic was on it for a long time and his numbers were stable. I recommend it. Most pet supply stores carry it.

I agree with the girl above, if you have the time feed her small portions at a time so she's not gulping it all down. If your talking whole portions like a chunk of chicken you definitely should make them into tiny dime sized pieces and like a spoonful of the pieces at a time, it's too much food at once. You know how if you give a baby a whole cookie they'll choke because they jam into the mouth all at once? Maybe her intake just needs to be regulated, but I'm no expert i just have always had animals and no money for vets. Good luck.

There is no such thing as a hypoallergenic breed, but there ARE low allergen breeds. Before you invest in a cat, your father needs to see an allergy specialist to determine if he is healthy enough to stand a cat and visit a cattery (you will almost definitley need to get a purebred) to see if the cats set off his allergies. I believe that ragdoll cats are considered low allergen, but i'm not sure.

She is probably just eating too fast. If you can give her her portions of food a little at a time that might help. give her a little bit of food, let her eat it, wait a couple minutes and give her more. Other than that I don't know what it could be besides that or hairballs.
