A climbing vine plant that cats are attracted to; possibly related to catnip or other feline-attractant plants.
Compound of cat + vine, describing a plant that grows as a climbing vine and has feline-attracting properties. Likely a folk term or regional plant name rather than a scientific classification.
Cats are weirdly picky about plants that get them high—catnip, silvervine, and valerian affect different cats differently, and about 1 in 3 cats doesn't respond to catnip at all, making it genuinely mysterious why some cats go crazy and others ignore it.
