Pine needles won’t harm your pet, but there are plenty of dangers surrounding a Christmas tree. The tree should always be properly secured, and fragile glass ornaments should be kept off low-lying branches to avoid losing family favorites if your pet decides to play. If your cat is prone to climbing, leave ornaments off the tree for a few days to see if he will attempt to climb it.
If you have a real Christmas tree, don’t add fertilizer to the tree water, and keep pets away from stagnant water in the reservoir.
Dangerous for: Cats and dogs.
Possible symptoms: Tree fertilizer and stagnant water may cause vomiting and diarrhea.
