Nepenthes species climb or trail via tendrils that extend from each leaf tip and terminate in a fluid-filled pitcher, which lures, drowns, and digests insects for nutrients the surrounding poor tropical soil can't supply. Considered non-toxic to cats and dogs — the digestive fluid inside the pitchers is primarily water and enzymes, harmless to mammals on incidental contact.

Description
Most houseplant Nepenthes sold commercially are hybrids bred for easier indoor tolerance rather than pure wild species, which are often significantly more demanding of cool nights and very high humidity. Each leaf produces a tendril that extends and swells into a pitcher trap, colorful and often patterned, that fills with the plant's own digestive fluid. Best displayed in a hanging basket where the pitchers can dangle freely — their trailing habit and habit of attracting curious hands (or paws) makes this the most practical way to grow them indoors.
Detailed Care
HumidityWants meaningfully higher humidity than typical home levels; low humidity is the most common reason pitchers fail to form or dry up. A terrarium or greenhouse cabinet suits it well.
WateringKeep soil consistently moist; use distilled, rain, or reverse-osmosis water where possible, as with most carnivorous plants — mineral buildup from tap water can stress the roots over time.
FeedingDo not add human food to pitchers. An occasional live insect is useful but not essential — hybrids grown as houseplants tolerate long stretches with no prey at all.
Cause of DeathLow humidity leading to pitcher loss over time, followed by mineral buildup from hard tap water.

Considered non-toxic to cats and dogs. The pitcher fluid is primarily water and digestive enzymes and is not known to be harmful on incidental contact or minor ingestion, though eating a large volume of any unfamiliar plant material can still cause mild digestive upset.
