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.
