Instructions
Place the poinsettia and other toxic plants like mistletoe on hard-to-reach shelves or in rooms that are usually locked or inaccessible to your cat. Sure, cats are notorious for getting into even the most far-off corners of your house, but you can keep plants away from them if you can think like a cat.
Put plastic bags or aluminum foil underneath your plant. Cats dislike walking or stepping on these materials.
Gain your cat's attention. A happy and involved cat is less likely to gnaw on a poinsettia. Buy some new cat toys or give him some extra treats.
Invest in some feline training. Cats don't respond to disciplinary training the way dogs do, but repeated admonitions can keep your cat away from the poinsettia, at least for a while.
Mist your poinsettia with a special spray that gives off an odor or flavor that cats dislike. There are several brands available at your local pet store. These sprays are not harmful to pets or humans. Cats just hate the smell and taste and are likely to leave the poinsettia alone.
How to Keep a Cat Away From Poinsettias
Contrary to popular folklore, poinsettias don't instantly cause cats to get violently sick or die, but they do cause serious gastrointestinal problems in felines. As a precaution, take your cat to the vet if it has ingested poinsettia leaves. If you own a cat, there's no reason you can't enjoy a poinsettia during holiday time. With a little planning, you can keep a cat away from your poinsettias.
