Yellow: with caution
A few drops are no drama, but olive oil is not a good idea as a home remedy. Chewy's veterinarian-approved guide expressly advises against giving oils such as olive oil, coconut oil or butter to a constipated cat. The high fat content is not healthy for them.
Why the traffic light is yellow
There are hardly any veterinary statements regarding olive oil in particular, and none of our sources classify it as poisonous. The problem is the fat. Oil is almost pure fat and therefore very high in calories. When it comes to coconut oil, veterinarian Jennifer Coates at PetMD describes that too much of it makes you fat and can cause diarrhea. From what we know, the same goes for other cooking oils.
High-fat foods can cause vomiting and diarrhea, and possibly pancreatitis in some animals, according to the ASPCA. Many cats are also too round rather than too slim, as veterinarian Sandra C. Mitchell notes at PetMD. A good cat food already contains all the fats your cat needs.
What you should pay attention to
- Not for constipation: If your cat doesn't defecate, it should be taken to the vet's office. Chewy does not recommend using oil as a home remedy.
- Frying fat is taboo: Pan oil often contains onions or garlic, both of which damage red blood cells, according to the ASPCA.
- Meat without oil: If you prepare meat for your cat, do so without butter, oil or seasonings, according to PetMD.
- Fish in Oil: According to PetMD, canned fish in its own juice is a better choice than fish in oil.
What to do if your cat has eaten olive oil?
If she has licked a little oil from the plate or salad bowl, watch her. Soft stools or one-time vomiting may occur. If garlic or onion was involved, call the vet's office. This also applies if diarrhea lasts longer than a day or your cat appears weak.
If poisoning is suspected, go to the vet immediately or to the veterinary emergency service.
Treats and extras are part of the daily ration. According to Cornell, they should make up no more than 10 to 15 percent of daily calories, and oil quickly depletes that budget.
