The details

Holly is a classic of winter wreaths and garlands, which puts it at nose height for dogs and within reach of cats who climb. Poisoning is usually mild because the prickly leaves discourage pets from eating much, but the bright berries attract puppies. Artificial holly berries can be a choking hazard too.

Keep wreaths on the outside of the door, and sweep up fallen berries and leaves.
