When your cat throws up his meal immediately or very shortly after eating you may assume the cause is that the brand of food isn’t good or doesn’t agree with your cat’s digestive system. However, this is not always the most likely cause of the vomiting.
We feed our kittens on a rotation of three flavors of Hills minced wet kitten food. My kittens have eaten this food since we adopted them (around 7 months ago) and they have always eaten well and kept their food down. Recently Hills came out with a new variety of kitten food, which is chunks and gravy. My kittens LOVE this food. Since we’ve been feeding them this new variety (2 weeks) they have each thrown up one time immediately after eating.
Eating too fast is a common cause of vomiting immediately after eating a meal. Your cat may love the food so much that they eat it really quickly, not taking the time to chew. When large chunks of food enter the stomach (such as wet food chunks or whole pieces of dry food) this can cause vomiting. When my kittens have vomited their meal it essentially looks exactly the same as it did straight out of the can and I can tell they have not chewed the chunks. In fact, my cats will try to eat the vomited food because they love it so much! Personally, I don’t let my kittens eat the vomited food because I suspect it would upset their stomach again. I wait for a while so that their stomach settles down and give them a new serving of either minced wet food or small sized dry food.
Another reason your cat may eat too quickly, causing vomiting, is that they feel threatened or in competition with another pet in the household. If your kitten or cat feels like their food is going to be taken away before they have finished, they may try to eat too fast. I have noticed this behavior in cats that have been rescued as strays because this is the behavior they would have to use in the wild. Cats would have to eat any prey quickly so other predators didn’t steal it.
Here are a few ways to make it easier for your pet to eat and prevent vomiting. Mash chunky wet food with a fork before feeding it to your cat. The smaller pieces are less likely to upset the stomach. If you have multiple cats, trying feeding them separately so they don’t feel the need to compete for their food. If these methods don’t work or your suspect there is a different cause of your cat’s vomiting, contact your veterinarian.
