Will pansies make a cat sick?

Yes, pansies are poisonous to cats. They belong to the violet family, which contains saponins, a compound that can cause vomiting and diarrhea in cats. Pansies also contain calcium oxalate crystals, which can irritate the mouth, throat, and stomach of cats. In some cases, pansies can even cause more serious health problems, such as kidney damage and respiratory distress. If you think your cat has eaten a pansy, it is important to contact your veterinarian immediately.
