My cat is throwing up white foam.

Customer Question

My cat is throwing up white foam. He is about 10 years old and an indoor cat. We have three other cats and they all eat the same food and water and have not had any problems.

Hi Grace,

Does he eat dry food?

Is he able to urinate fine?

When did he eat last?



Customer: replied 9 years ago.
All four cats eat Iams brand dry food and have for at least seven years. I have not noticed any changes in his urinating or eating habits, but that is only because I have failed to notice. His throw up does not contain any food. He usually drinks water from a bowl, but this morning he wanted water directly from the faucet, which is something he never does.

Dear Grace,

I am so sorry your boy is not feeling well.

Cats dont get "bugs" but they do get infections. I would suspect an abscessed tooth, an infection or a GI upset or acid reflux. Even though he may not appear underhdrated, he still can be a bit,and be drinking from the faucet in a despirate attempt to restore his fluid balance.

Feel all over his body and see if he reacts to any painful spots.

Make sure he is able to urinate. He should be seen ASAP if he can't!!

Cats that eat dry can have bouts of dehyration.Indigestion is caused by inadequate chewing. Vomiting is very common. When acid reflux builds up in the stomach, they begin to vomit. Even if they have always eaten this,, they often become intolerant to corn and gluten which are used as filers in most supermarket cat foods.Vets push science diet because they sell it but it is not a great food as it too contains corn and gluten.

Lack of fluid in the bowel also leads to vomiting, Ingested hair can also be a factor.Anorexia for any extended time leads to liver damage and causes nausea and vomiting as well.

I would add some canned food for him

Serve the two foods separately - do not mix them - add a half pepsid a/c tablet, crushed up into the wet food one time a day.

Put hairball remedy or even plain vaseline on his paw for himto lick off as well.

If his tummy needs a rest, feed baby food with no onion or garlic for a few days.

If he wont eat, and your cat is not diabetic begin by giving him two droppers (cc size) of unflavored pedialyte every ten minutes for an hour. Next water down(plain water) canned cat food or baby food chicken or turkey with no onion or garlic and give only one dropper every ten minutes for another hour. Wait two hours and repeat both. When he feels hydrated he will lick up the gruel on his own.

Give him droppers of unflavored pedialyte a few times a day to make sure he stays hydrated.

If he continues to vomit and cannot keep anything down her should be seen right away.

Please let me know how he is doing. I will always be here for you.

I hope he feels better very soon.

Sincerest best wishes,
