Cactus are not toxic if consumed, but their sharp spines make them hazardous to pets all the same. Take particular care with members of the Opuntia (Prickly Pear) genus. They don't always have long spines, but they do have tiny, barbed glochids.
What cactus plants are poisonous to cats?
Many succulents in the euphorbia genus, such as the pencil cactus and crown of thorns, are poisonous to both cats and dogs. Symptoms of poisoning from ingesting this succulent range from gastrointestinal upset to skin and eye irritation.
Luckily, most succulents are considered non-toxic and are harmless to pets when ingested. Others contain skin irritants that can cause minor skin irritations, and some can cause mild symptoms when ingested.
