Why is my 11-year-old cat vomiting unchewed food after eating?

Updated On September 23rd, 2025

Pet's info: Cat | Russian Blue | Male | neutered | 10 years and 7 months old | 16.5 lbs

My 1/2 Russian Blue mix keeps vomiting shortly after eating.Not every time but almost daily.It appears the dry food isn’t chewed up.this is also w/ wet food.Seems to be happening more often in the past few months.So we slowly changed his royal canin weight control to their sensitive stomach but the issue continues.He’s almost 11 & a little overweight but not much.He’s just large at about 16 1/2 lbs.Still active,eats & drinks normaly,& isn’t really showing signs of aging.What else can we try?

Marley is a very handsome boy! I'd have him checked out by a vet for a geriatric blood panel and urinalysis. In senior cats, there are medical conditions that can cause vomiting such as diabetes, hyperthyroidism, and kidney disease, and those tests I mentioned above can screen him for them. Should he have one of these, the vet can discuss treatment options with you. Please have him seen by a vet in the next few days. Best of luck.
