Reasons Cats Can’t Eat Vegetable Oil
1. Leads to Diarrhea
A concern that will be noted right away has to do with diarrhea.
Yes, the cat’s system can digest vegetable oil but that doesn’t mean the cat will be safe. Instead, the oil is going to go through the system and cause it to panic.
This includes causing diarrhea to the point it becomes difficult to handle. The goal is to understand what works best for your cat and isn’t going to lead to these types of unwanted symptoms.
Even if vegetable oil can be consumed in small amounts, it is not the first food you should be giving to your cat. The diarrhea they are going to deal with can be concerning and it is not something to take lightly.

2. Causes Nausea
One of the side effects has to do with nausea.
This will not be seen in all cats but is possible in smaller cats. This includes kittens that are not as capable of digesting a large amount of vegetable oil without symptoms.
If you are wondering “Can cats have vegetable oil?” it is best to look at this reason as a serious concern. Seeing your cat feeling nauseous is not a good sight and it is also going to make it harder for them to eat anything else during the day.
It is smarter to focus on keeping things as simple as possible by avoiding vegetable oil for cats. It is just not going to be a solution that will work out the way you want it to!
By using vegetable oil for cats at home, you are going to be opening them up to a symptom such as this one. It won’t be worth it.

3. General Fatigue
It is the fatigue that tends to become a serious concern with cats that eat vegetable oil.
When you ask “Can cats have vegetable oil?” you will want to account for everything and this includes their energy levels. A lot of cats are going to take the time to digest the vegetable oil and this can cause them to fall into a state of lethargy.
With larger cats, it might not be as noticeable.
However, smaller cats are going to have a reaction and it is something you are going to notice right away.
Focus on this factor if your cat accidentally eats a bit of vegetable oil.
If you notice this, it is important to make sure the vegetable oil is taken away from them and they are allowed to rest.
