Garlic bread, garlic aioli, creamy garlic pasta sauce, garlic wings, garlic broth — as far as flavors go, garlic is one of the most iconic there is. If vegetables were One Direction, garlic is Harry. It’s one of those foods that sticks out from the crowd. So it makes sense that we’d be tempted to share with our cats; don’t they deserve the best? Well, yes, obviously. But what’s best for you isn’t necessarily best for your pet. When it comes to garlic, cats lean more on the vampire side than the human one. So before dishing out a few cloves, read everything you need to know about feeding garlic to cats below. 

Can cats have garlic?

The quick answer: No — cats should never have garlic. According to veterinary nutritionist Dr. Marge Chandler, “Garlic is toxic for cats…and can result in a fatal anaemia.” 

Garlic is from the Allium family, which is the same family as onions — another food cats and dogs should avoid. Cats are even more susceptible to poisoning from garlic and onions than dogs; it only takes a few bites for snack-time to become dangerous. Every cat is different, but if you ask us, it’s definitely not worth the risk. 

Is garlic toxic to cats?

Yep, garlic is considered toxic to cats. The most typical reactions are vomiting, diarrhea, nausea, abdominal pain, and drooling. In more severe cases and high levels of garlic intake, garlic can damage red blood cells and cause them to rupture. This leads to an increased heart rate, increased respiratory rate, pale gums, weakness, collapse, and, in rare cases, death.

Symptoms can set in two to four days after garlic is consumed — so even if your cat seems to take well to garlic, get a vet’s input as soon as possible. Vets can sometimes help immediately by inducing vomiting (never induce vomiting at home — leave it to the pros) or administering activated charcoal. If the poisoning has already begun to take course, your cat may need IV fluids, a blood transfusion, and/or oxygen therapy. 

How much garlic is toxic to cats?

The amount of garlic it would take to poison your cat varies greatly depending on your cat’s weight, health, and breed. Often, a single clove of garlic can be toxic for a cat. That’s why it’s not worth risking giving your kitty even a little taste, no matter how grumpily they watch you eat your pasta.

Dried, liquid, raw, powdered, and cooked garlic are all toxic to cats; that means no sharing treats or meals cooked in garlic, either. As little as 1/8 teaspoon of garlic powder can be poisonous. If you take a supplement with garlic as an ingredient, even that can harm your kitty, so keep your cat away from the bottle or any dropped pills. 

Can garlic prevent fleas?

There’s a common conception that garlic can act as a natural flea preventative for cats. Unfortunately, it’s just not true. “Garlic is toxic for cats and does not provide any benefit for fleas,” Dr. Chandler says . “The concept is that a product from the garlic would come out in sweat; however, cats only have sweat glands on their paws, so [garlic is] not very useful even if it wasn’t toxic.”

Luckily, there are lots of non-toxic flea preventatives on the market. The good news is these options won’t stink up your kitty, but the bad news is you can’t throw the extra in your spaghetti — you win some, you lose some.
