No action needed. Hang it high if you want to keep the vines photogenic — that's plant care, not cat safety.

FAQ
My cat chewed a hoya vine — is the milky sap dangerous?
No toxin is on record. The ASPCA lists the wax plant (Hoya carnosa) as "Non-Toxic to Cats" with toxic principles given as "Non-toxic" — the milky look of the sap doesn't make it a poison. Pet Poison Helpline groups Hoya with popular plants that "could cause a bad taste in the mouth or mild stomach upset if ingested, but not likely an urgent trip in to see your veterinarian." Offer water, expect at most a brief upset stomach after a big chew, and call your vet only if vomiting persists.
