Onions are a part of almost every cuisine around the world. There are barely any dishes that don’t get a flavor enhancement with the addition of onions. This vegetable also comes with important vitamins and minerals.

Onions also help in fighting off bacteria such as E.coli. Additionally, onions can also help in improving your digestive health.

Can Cats Eat Onions?
So, are onions bad for cats? The short answer is a resounding YES!
Your cat would be very sensitive to onions and even a small amount can end up being life-threatening. It doesn’t matter how much onion or which type of onion you use – red, white, or yellow.
All kinds of onions are dangerous for your cat, even table scraps or a very small amount of onions.
Quantities do not matter, just steer clear. It is essentially food poisoning for felines.
Even if you cook the onions, it won’t make a difference. It would still be toxic to them whether they eat it raw or cooked. Even if you mix them with something else, the onion toxicity will still affect your cat.
Onion powder is another option that you may think might be given to your cat. But that should be avoided as well. If anything, onion powder is more harmful. The dehydration from the powder will increase the toxicity even higher.
People who tend to use onion powder in their dishes should make sure their cat stays away at all costs.
This goes the same for raw eggs and dairy products.

Can Cats Have Onions Safely?
Onions are part of a group of plants called alliums. Edible alliums, including leeks, garlic, chives, shallots, and spring onions. These are commonly found in most home kitchens.
The general rule is that the more your cat has eaten onions, the greater the effects. According to experts, if your cat eats around 5 gm of onion for every kilogram it weighs, then it can end up causing serious harm.
The toxic agent present in onions is the oxidant n-propyl disulfide.
When your cat eats a large quantity in a single sitting, it could be lethal. At the same time, if your cat has been eating smaller doses of onion, then the toxicity can build up over a period of time.
This could be from giving your cat foods that have trace amounts of onion as part of their ingredients.
Symptoms of Onion Poisoning in Cats
If your cat has ingested any onion, whether it’s by eating the vegetable itself or by taking a bit out of your food that contains onion, there are a few symptoms you can look out for to determine toxicity.
Your cat might be panting and could be lethargic, which is a sign that it’s suffering from the toxic substances that it has ingested.
If you see blood in your cat’s urine, then you should immediately take them to the vet for further checks.
The same is the case if you observe that your cat has an elevated heart rate.
Onion consumption will potentially lead to seizures, muscle tremors, or even a coma.
These symptoms may not appear immediately after consumption. If the dose is lower, it could take days or weeks for the symptoms to show up.
But if you are very sure that your cat has certainly eaten food that contains onion, then it’s best that you take them immediately to the vet even if they don’t show any symptoms. It’s always better to be safe than sorry.
