Stop cat from vomiting (cancer of the stomach)?

I have a cat that was just diagnosed with a mass in his stomach. We had gone for months with him throwing up constantly but then his weight changed significantly and we took him for a sonogram.

He wasn't eating and we thought it was the end. He is now on steroids (5mg - prednisolone) and he's eating and drinking daily.

The only problem is the vomiting has reoccurred and because of the steroids he is starving all the time.

We feed him DM food as he was a diabetic but has been in remission for over a year. Any suggestions would be greatly appreciated.

I have another cat in the house who is now starving all the time and has always been my chubby kitty. They say cats imitate each other.

I really look forward to suggestions.

Editor's note: I'm sorry to hear that your cat is sick. I'm wondering if the vet has an opinion on the exact cause of the vomiting?

According to PetPlace, among others, both increased appetite and vomiting are side effects of prednisone/prednisolone.

I spent some time on steroids (prednisone) as a kid (my doctor used to give them out like candy every time someone was sick). They make you want to eat your pillow.

Is it possible that his level of hunger causes him to eat to much too fast? Cats really don't chew their food, and a hungry cat will often eat so much in one sitting that they throw up.

If your vet approves, would it be possible to break up the mealtimes into smaller, more frequent sessions?

I would run all changes by your vet since these steroids have an impact on metabolism, and with your cat's history of diabetes, this becomes even more significant.

I wish I could be of more help. Please keep us updated on his progress.

Additional note: This submission was originally left as a comment on this page... My cat seems to throw up every time she eats. I thought I'd post it here to see if we can reach a wider audience and get some more help.

My cat suffers the same problem
by: Anonymous

Billy was diagnosed with intestinal cancer after many, many blood tests and a sonogram which all ruled out anything being wrong. The Dr. finally performed exploratory surgery and found the cancer. I was at the end of my rope and my poor Billy was down to 6 pounds. I had been through all the cat food changes (the ones without wheat/corn/rice worked best for him) before finally begging the Dr. to PLEASE DO SOMETHING which led to the surgery.

He is on prednisone twice a day and so far is doing well. He has gained 5 pounds and is now a little porker. But, I know it is just a temporary fix and I will lose him in the near future.

But one thing I do is feed him just a little food (no corn/wheat/rice) 3 times a day. I measure out about 1/2 to 3/4 cup of dry food in the morning and feed him small amounts at a time. If I have to go into the office for the day, I still only leave a small amount in his food bowl and then leave another small amount hidden under the bed or in the closet where he has to hunt it down. He almost always finds it but it takes him a while so he doesn't eat it all at once. So far he is not throwing it up and seems to be doing so much better than the previous 2 years.
