Is colorado blue spruce safe for cats and dogs?
Mildly. The ASPCA flags colorado blue spruce as mildly toxic to cats and dogs — a chewing pet gets oral irritation and drooling rather than a medical emergency, but it is still worth a high shelf. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. Picea pungens is not listed as a toxic plant by ASPCA. However, the sharp, stiff needles can cause physical injury to pets' mouths and digestive tracts if chewed, and resinous compounds may cause mild gastrointestinal upset. Not considered a significant poisoning risk but ingestion of needles or cones is not recommended for cats, dogs, or horses.
