Is string of needles safe for cats and dogs?
Mildly. The ASPCA flags string of needles 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. Ceropegia linearis is not individually listed by the ASPCA. The genus belongs to the Apocynaceae family; while many Ceropegia species are considered low-risk, the absence of a confirmed ASPCA non-toxic listing warrants a conservative mildly-toxic rating. Keep away from cats and dogs.
