If you see your cat vomiting white foam, you may be concerned. After all, humans tend to vomit due to an illness — sometimes a severe illness. However, a cat throwing up white foam is actually quite common. If you notice your cat exhibiting such behavior, it’s important to know the possible causes. Then you can decide whether you should take your feline fur baby to the vet.
One of the most common causes of a cat throwing up white foam is a hairball. Hairballs occur because when cats groom themselves, they end up swallowing some of their hair. This turns into a hairball in the cats’ digestive systems. Cats should be able to digest this fur — after all, they eat critters with fur and are constant groomers. When hairballs become a problem, it is usually a sign of a lack of digestive enzymes, a problem that is particularly prevalent in older cats.
2. Dietary Changes
Another factor that can cause your cat to throw up white foam is dietary change. Cats sometimes protest changes to their diet by rejecting a meal or eating later than normal. Whether a cat eats or not, her body will produce the digestive juices necessary to break down food. The result is often vomiting.
For the same reason, a change to your cat’s feeding schedule can lead to vomiting white foam.
3. Stomach Inflammation
When stomach inflammation (called gastritis) is the cause of your cat throwing up white foam, it may be accompanied by a lack of appetite. Your cat may vomit bile or blood in addition to the white foam.
Causes for Concern When Your Cat Is Throwing Up White Foam
If your cat is just responding to a change in feeding or has the occasional a hairball, you can relax. However, if your cat’s vomiting is due to gastritis, a visit to the vet may be in order. Other symptoms of gastritis may include sluggishness, dehydration, depression, and stomach discomfort.
Cats eat hair; that’s a fact.
