It is not recommended for cats to eat raw bacon.
Cats are obligate carnivores that need animal-based flesh in their daily diet to function at their best. However, instead of bacon, cats are commonly fed cooked and unflavoured beef, chicken, and turkey. This is because the cured meat that comes from boneless pork cuts is high in fat, salt, seasonings, and additives (such as nitrates, nitrosamines, and nitrites)—all of which are not good for cats.
When served raw, bacon also poses the risk of passing on harmful pathogens and parasites to your cat. Contaminated raw bacon can cause salivation, vomiting, diarrhea, twitching and fitting, difficulty in breathing, shock or collapse, skin inflammation or swelling, and depression or coma. Your cat may also display changes in her drinking, eating, peeing, and pooping habits.
What to do if your cat accidentally eats raw bacon: Try to find out how much raw bacon your cat ate. Check the label to discover all the ingredients used to cure the meat. Contact your veterinarian immediately if it includes toxic flavourings such as garlic or onions.
Monitor your cat for any of the symptoms mentioned above. Additionally, watch for signs of salt poisoning such as decreased appetite, lethargy, incoordination, excessive thirst or urination, tremors, and seizures.
In summary: Refrain from giving your cat raw bacon to avoid health complications. A tiny piece of cooked bacon may be fed to your cat as an occasional treat. But giving it on a regular basis may lead to dehydration, high blood pressure, obesity, clogged blood vessels, and salt poisoning.
