If you’re a furbaby parent, you’ll know nothing is off-limits. Cats and dogs are carnivores, but that won’t stop them from nibbling on anything from your slippers to your most prized iris flower. They may do this for nutrients and fiber, or out of boredom. However, irises are poisonous to cats and dogs. If your pet has consumed any part of the iris plant or flower, then you should contact your vet. They can administer charcoal treatment to make them regurgitate. Since all parts of irises are poisonous to cats and dogs, if they show interest in eating your plants, then take precautions. You must fence off outdoor plants. Refrain from keeping any iris plant inside if you have a cat, since there are no parts of the home, your cat can’t reach, including high shelves and mantelpieces.
