Rogaine Killed My Cat?

When I searched online ”Rogaine killed my cat”, I found this following heart-breaking story in a cat forum.

I’m not even sure how it happened. One minute my cat, Snuggles, was rubbing against my leg and purring. The next she was lying on the floor, motionless. There was a small bottle of Rogaine sitting on the coffee table and I can only assume that’s what killed her”.

This is truly a sad story. But can Rogaine kill a cat? We will answer this question along with other things related to Rogaine and cat. Let’s start with the most important question:

Is Rogaine Poisonous to Cats?

Yes, Rogaine is extremely poisonous to cats. It is important to keep the product out of reach of pets, as they may be tempted to lick it off your head or skin. If ingested, Rogaine can cause severe gastrointestinal upset in cats.

Symptoms may include vomiting and diarrhea. If you think your cat has ingested Rogaine, please contact your veterinarian or local animal hospital immediately.

Symptoms of Rogaine Poisoning in Cats?

The symptoms of Rogaine poisoning in cats vary depending on the dose and the cat’s age. A large dose can cause vomiting, diarrhea, excessive salivation, disorientation, hyperthermia (elevated body temperature), seizures and death. Smaller doses may cause mild symptoms such as drooling or loss of appetite.

How Much Rogaine is Toxic to Cats?

In short, even a single drop or lick of Rogaine is toxic to cats. That’s because the active ingredient in Rogaine is minoxidil, which is a vasodilator that causes blood vessels to expand. This can treat hair loss in humans, but for cats it can have serious repercussions.

How Do I Protect My Cat from Rogaine?

There are a few things you can do to protect your cat from minoxidil.

First, keep the medication out of reach of your cat. If your cat comes into contact with it, then they should be washed off immediately with cold water. Don’t use warm water or soap as these will increase absorption of the product by the skin.

Second, talk to your veterinarian about any potential side effects of minoxidil and how to best avoid them.

What Happens If My Cat Licks Rogaine?

If your cat licks the Rogaine that you applied to your head, it can cause some severe side effects. This is because minoxidil is not intended for cats and can be toxic to them. If a cat licks the product from your head, it will probably lick its paws and ingest the drug.

If your cat ingests any of the topical minoxidil (Rogaine), call your vet immediately. They will probably want you to bring your cat in so they can assess its condition and provide treatment if necessary.

Find Out Whether Other Things That Can Kill Your Cat


We all love our furry friends, and we’ll do anything to keep them safe and healthy. So when we heard that a popular hair loss treatment, Rogaine, might be harmful to cats, we were understandably concerned. It turns out that Rogaine contains minoxidil, which is toxic to cats if they ingest it.

Even small amounts can cause vomiting, diarrhea, seizures, and even death. And since cats are curious creatures who like to explore everything with their mouths, it’s easy for them to accidentally get into a bottle of Rogaine (or come into contact with someone who’s using it). If you use Rogaine or any other products containing minoxidil, be sure to keep them well out of reach of your feline friends.

And if you think your cat may have ingested some minoxidil, call your veterinarian immediately. It could save their life.
