Sometimes our cats eat things they shouldn’t. This may include plants, parts of cat toys, string, or even medication meant for other pets, such as our dogs. Even when we do everything possible to keep our cats from access medications, accidents do happen.
Has your cat eaten Vetmedin? Are you worried Vetmedin will make your cat sick? If so, then you’ve come to the right place.
In this article, we’ll take a look at Vetmedin and whether or not it can make your cat sick. Let’s get started!
What is Vetmedin?
Vetmedin is a veterinary prescription only medicine (POM-V)that’s for dogs. It treats mild, moderate, or severe congestive heart failure in dogs, caused by two different types of heart disease – Mitral valve Disease, and Dilated cardiomyopathy. This medication works in two ways – the first is by opening up blood vessels carrying blood away from and to the heart, therefore reducing the work the heart has to do to transport blood around the body. It also increases the pumping action of the heart by improving the efficiency and strength of the dog’s heartbeat.
You may also hear this medication called Pimobendan.
While this medication is safe for dogs, what happens if your cat eats Vetmedin? Will Vetmedin make your cat sick?

Treatment of Vetmedin Ingestion in Cats
When you reach the vet’s, they will first conduct a complete physical exam of your cat. They will also order lab work including a blood test and urinalysis. They will check your cat’s breathing rate and heart rate.
If your cat has recently eaten the medication, the vet may induce vomiting and/or use gastric lavage to wash the medication from your cat’s stomach. Activated charcoal may also be used to keep your fur baby’s body from absorbing the medication.
The vet will also treat other symptoms such as elevated blood pressure and more. Your feline companion may also require an IV line for fluids and to make it easy to give her necessary medications.
Your vet will also want to monitor your cat’s heart and lung function, which may mean your fur baby has to stay in the hospital a day or so.
The prognosis for cats that have eaten Vetmedin is very good if they receive prompt medical treatment.
