Avocados are a total superfood for us humans, but when it comes to our feline friends, they’re a definite “no-go.” The culprit is a toxin called persin. While it doesn’t bother us one bit, it can be deadly for cats. Here is the lowdown on why you should keep the guac away from your kitty.
Where is persin found?
This toxic compound is found in the avocado fruit itself, but it’s most concentrated in the pit. If you’re like me and love growing your own little trees, be extra careful: the entire plant—leaves, stems, and all—contains the toxin. Since cats (and dogs too!) love to nibble on indoor greenery, make sure your avocado plants are kept well out of reach of your four-legged roommates.
How does the toxin affect cats?
Persin is fat-soluble, which means it can start irritating the stomach and intestinal lining almost immediately. If it makes its way into the bloodstream, the consequences get much more serious, leading to heart rhythm issues or even heart failure. Generally, the smaller the cat, the faster and more severe the reaction will be. Usually, the first sign of trouble is vomiting, as the body tries to get rid of the poison.
What should you do?
If your cat accidentally sneaks a bite of avocado or decides to snack on your plant, call your vet right away. They’ll know exactly what steps to take to get your pet back on the road to recovery.
Pro Tip: Cats are obligate carnivores, meaning they thrive on meat. It’s always best to skip the table scraps and stick to high-quality cat food specifically formulated for their needs.
