Advantage Killed My Cat?

When I searched online ”Metronidazole killed my cat”, I found this following heart-breaking story in Reddit.

”I’ve cried every day since the sudden death of my cat 3 weeks ago. My 8-year-old healthy cat died suddenly, due to Advantage II poisoning. Our big kitty loved going outside. We would only let him out when we were out there too, and he would spend his time going through my flower beds, watching the birds in our yard. The downside of this, is he ended up getting fleas last fall. So we went to PetSmart and picked up a single application pack of Advantage II, and applied it. It worked fine and killed the bugs.

Fast forward to 4 weeks ago. We spent most of the summer just making him wear a flea collar when he was out. He was an escape artist though and would get out of them, plus he really hated it. So, we bought a multi pack of Advantage II for large cats off Amazon.

We applied it to him, per the instructions. About a week later, we woke up, and he was puking on the floor. We thought little of it, as he did that once in a while. I leave for work early, but my husband was still home with him. He text me and said our kitty was drooling a little, and thought we should take him in. We called the vet and were set to take him in. Unfortunately, he never made it. He ended up seizing and died’‘.

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

Is Advantage Poisonous to Cats?

No, advantage is not poisonous to cats. Though the above story is unfortunate, in fact, it’s a topical flea treatment that’s specifically designed for cats. When used as directed, it’s safe and effective at preventing and treating flea infestations.

What Happens If a Cat Licks Advantage Flea Treatment?

If a cat licks Advantage flea treatment, the active ingredient in the treatment, imidacloprid, will be ingested. Imidacloprid is a neurotoxin that can cause vomiting, tremors, and seizures in cats. If a cat ingests enough of the chemical, it can be fatal.

Can Flea Treatment Burn Cats?

There is a lot of misinformation out there about flea treatment and whether it can burn cats. If used correctly, flea treatment will not burn your cat. However, there are a few things to keep in mind when using any type of flea treatment on your pet.

Foremost, always follow the directions on the product label. This may seem like common sense, but it’s important to remember that different products contain different active ingredients and therefore require different application times and/or dosages. Applying more or less than what is recommended might lead to adverse reactions in your pet.

Second, be sure to apply the product evenly over the entire body, paying special attention to areas where fleas are most likely to congregate (such as the base of the tail). Avoid getting any product into your cat’s eyes, nose, or mouth as this could also cause irritation. If you’re using a topical spot-on treatment, be careful not to get any on yourself either – always wash your hands thoroughly after application!

And finally, don’t forget that regular grooming is an important part of keeping your cat healthy and free of Fleas & Ticks. Daily brushing will help remove any loose dirt and debris from their coat while also distributing their natural oils which help keep their skin healthy. Plus, it’s just a good way to bond with your feline friend!

Why Can’t Cats Use Advantage II?

Advantage II for cats is a flea and tick treatment that can be applied to your cat’s skin. It contains imidacloprid, permethrin, and pyriproxyfen, which are all ingredients that prevent fleas from biting your cat and will also kill ticks.

You can use Advantage II that are specifically made for cats. Don’t use Advantage II that are designed for dogs on cats because it can be harmful to your feline friend.

Why is My Cat Acting Weird After Advantage?

If your cat is acting weird after using Advantage, it’s probably because the product is causing some irritation. Advantage contains chemicals that can cause skin and eye irritation in cats. If you notice your cat scratching a lot, or if its eyes look red and irritated, stop using the product and take your cat to the vet.

Side Effects of Advantage II for Cats

Advantage II for Cats is generally safe when used as directed. However, some side effects may occur including:

  • Diarrhea
  • Vomiting
  • Loss of appetite
  • Lethargy

If your cat is displaying any of these symptoms after taking Advantage II, it’s important to contact your veterinarian right away. These side effects can show a more serious problem and the sooner you get your cat checked out, the better.

Is Advantage Safe for Cats If Licked

Advantage flea treatment is a popular choice for many pet owners, but there is some debate over whether it is safe for cats if they lick it. The active ingredient in Advantage is imidacloprid, which is a neurotoxin that can be harmful to animals if ingested in large quantities. However, the amount of imidacloprid that would be present on your cat’s skin after application is tiny and unlikely to cause any harm.

Find Out Whether Other Things That Can Kill Your Cat


If you’re a pet owner, then you know how important it is to keep your furry friend healthy and safe. Unfortunately, sometimes even the most well-meaning pet owners can unintentionally do harm to their pets. For example, did you know that using Advantage flea and tick treatment on your cat could actually be deadly?

Advantage is a popular flea and tick treatment for both dogs and cats. It’s applied topically and is supposed to be safe for animals of all ages. However, there have been a report of adverse reactions in cats, including death.

The active ingredient in Advantage is imidacloprid, which can be toxic to cats in high doses. Symptoms of imidacloprid poisoning in cats include drooling, vomiting, lethargy, seizures, and difficulty breathing. If you suspect Advantage or any other product containing imidacloprid has poisoned your cat, please contact your veterinarian or the ASPCA Animal Poison Control Center immediately.
