No, seriously, some cats adore olives. We’ll talk about the reasons a little later, but well, cats often eat and do strange and weird things — and it’s not a problem… unless their eating habits and food preferences are harmful. You have to be very careful with the food you give to your cat if you want him to stay healthy. Of course you do!

In this particular article we’ll talk about the olives. We know that the cat owners often ask the questions like “are olives safe for cats?”, and that’s exactly why we’ve decided to write this short article. Your cat deserves to eat only healthy food, agree?

Do Cats Love Olives?

The short answer is: yes, they do. However, they don’t just love olives because they are tasty — according to the cat experts, olives work in a similar way as the catnip (catmint). Why do cats like olives? The reason why it has such an effect is called “methyl cyclopentane monoterpene nepetalactone”. It’s a chemical compound, which has a mind-altering effect. Just like human drugs, basically. No, we don’t wanna say that your cat is a drug addict… but he definitely gets high with olives, as well as with catnip. Is it a problem?

No, it isn’t. However, both black and green olives safety issue is a very deep question, when it comes to cats — and we’ll try to answer all your questions here. Let’s go.

Safety Concerns

In general, healthy cats may eat little amounts of olives without any ill effects, but higher amounts can be dangerous. Before deciding to give your cat olives, familiarize yourself with the hazards.

Olives are typically preserved in a high-sodium liquid, which can result in salt sickness. Since the renal failure, which is lethal for cats, is linked to all of the accompanying symptoms, they are all very serious. A few signs of sodium positioning include decreased appetite, tremors, vomiting, diarrhea, and dehydration.

Similar to adult cats, kittens may experience stomach trouble after eating olives because of the laxative effects of the fruit’s fiber. Young cats may thus be more vulnerable to diarrhea, which causes dehydration.

You should also keep your diabetic cat away from olives because consuming olives might cause insulin sensitivity.

The second thing you have to know is: yes, the olives can be bad for cats. Once again, we’ll talk about the chemical composition of olives in the next paragraph, not here.

Here we’ll talk about salt. The thing is, the olives are soaked in juice when you buy a jar of olives, and this juice is extremely salty. Of course, cats love salty stuff, but it can be a problem — the salt can lead to the sodium poisoning, and it’s a very serious problem for the cats. If your cat suffers from vomiting, diarrhea, tremor or seizures after eating olives, call your vet right now — this condition can be very dangerous.

If you wanna give some olives as a treat to your cat, try to find the unsalted ones. They are a little more expensive, but it’s definitely worth it when it comes to the health of your cat!

Can Cats Eat Black Olives as a Treat?

However, they do also contain vitamin C, vitamin A and some antioxidant compounds, which are actually good for your cat’s health — so there are no special problems with black olives. They are as bad and as good as green olives, that’s all you have to know.
