I was talking to a friend about her cat. Apparently, her cat went through a period where should would not eat. Period. Seriously. Strange, right? I hadn’t heard of this. Goodness knows, cats are finicky. Tell me about it. But not eating. It got to the point where she had to use an appetite stimulant for her cat. A what? Is that even a thing?

Yeah, it is actually. I looked it up. For any number of reasons that I’ll go into in a bit, your cat can suffer from a lack of appetite. Some of those reasons can be super serious involving everything from a nasty infections and dental disease to kidney disease and parasites. Yuk.

Why Do Cats Lose Their Appetite?

One common culprit is dental disease. A tooth ache. I don’t want to eat either when a molar is throbbing. But it could be any number of other conditions, such as kidney failure, pancreatitis, infections, and even cancer. Then there are the gastrointestinal problem like the aforementioned parasites. So a bunch of ailments can cause your cat to stop eating.

There other less ominous reasons your kitty has stopped eating. Have you had your cat vaccinated recently? That may be the reason. Cats can have adverse reactions to the shots and a side effect is that they lose their appetite. It typically doesn’t last. Anxiety and depression are also conditions that will lead your cat to stop eating. This the issue that my friend thought was the problem with her cat. Your cat is a sensitive animal (we all know that) and sometimes changes in schedules or new people in the household can throw your cat into a funk.

Two other causes are sometimes are related either travel or a new diet. Cats are total creatures of habit. So if you switch up their meals, it may take your cat a while to adjust. WebMD advice is good here:

“Keep in mind that cats, in general, take a long time to adjust to new types of food, so a recent change in diet could be the culprit.”

And, of course, travelling may cause appetite loss as some cats get motion sickness. It’s true. And what’s more, your disrupting your cat’s daily routine. All reason she may stop eating.
