I personally have spider plants (mildly hallucinogenic, one of my recent fosters was a complete drug fiend about them), schefflera (cats don't touch it), jade (they munch on the leaves sometimes), and some various succulents (cats sleep on them and smoosh them to death).
Catnip is an herb that, when smelled by a cat, can affect behavior. About 60% of cats will have a behavioral reaction to catnip. The effects of catnip varies from cat to cat, but can include signs of happiness, hyperactivity, or even aggression.
This plant is also referred to as Ska Maria Pastora, Diviner's Sage, Salvia, and Seer's Sage is a psychoactive plant that causes hallucinatory experiences. Salvia is an unassuming herb that belongs to the mint family and has gained renown for its growing popularity.
Jimsonweed (Datura stramonium)
The leaves and seeds contain potent alkaloids (hyoscamine and hyoscine) that cause hallucinations. Used ceremonially by a number of indigenous peoples, jimsonweed acts as a deliriant and can produce intense spiritual visions.
Hallucinogenic Mushrooms
Certain Psilocybe and Panaeolus spp. contain toxins with strong hallucinogenic properties. Psilocybin, a tryptamine derivative, is the most important toxic component enhancing serotonin levels in the CNS. These fungi, known as “magic mushrooms”, are ingested deliberately.
The most dangerous plant is the lily - all parts are toxic. However, there are other plants and flowers, both indoors and outdoors, that can be harmful to cats.
Silvervine
If your cat doesn't respond to catnip, there are several alternatives. Silvervine tends to be the most effective of them. Native to the mountainous regions of China, Japan, and Russia, silvervine is a member of the kiwi family that can produce quick euphoric effects in cats.
Can my cat overdose on catnip? Cats can't technically 'overdose' on the smell of catnip, however, they shouldn't eat too much of it in one go, as they may experience some mild gastrointestinal distress, such as vomiting or diarrhea. If this occurs, remove the catnip from your cat's environment.
Cats with FHS often show bizarre behaviors, ranging from occasional lack of activity (freezing) to apparent hallucinatory behavior. Genetic factors appear to play a role. Schizophrenics also display bizarre behaviors, sometimes showing a lack of activity.
The disappearance could mean that the cat is injured, trapped, or deceased within its territory. Or perhaps the cat was transported out of the area—either intentionally (by an irate neighbor who trapped the cat) or unintentionally (by the cat climbing into an opened parked van).
Nepetalactone triggers a sense of euphoria in the brain of the susceptible cat, which produces the “high” that is sometimes described as similar to either marijuana or LSD in humans. The response to catnip typically lasts for about 10 minutes before wearing off.
Popular options for calming herbs for cats with cat anxiety are catnip, chamomile, hops, valerian root, lemon balm, skullcap, and California poppy (don't worry: it doesn't have any opiates).
wake up and smell the roses. On top of roses, other plant and flower scents cats like include sunflowers, grass, chamomile, valerian and olive trees, oils, or leaves. Keep in mind olive can produce similar effects to catnip. Before you go wild in the garden or home, remember to read up on poisonous plants.
Cats and the Variegated Spider Plant have a complex relationship. While non-toxic, the plant can still cause mild hallucinogenic effects in felines. Keep an eye out for vomiting or diarrhea—classic signs of gastrointestinal upset. Other symptoms may include lethargy, drooling, or a sudden burst of hyperactivity.
Valerian. Its clustered white flowers will attract pollinators to the yard and its root is sometimes employed as a calmative and sleep aid in humans, but this pungent plant is also a stimulant for cats and triggers a response similar to that of catnip.
The leaves of catnip (Nepeta cataria) tend to be more triangular in shape, with a cordate or heart-shaped base, and lighter undersides. Those of horehound (Marrubium vulgare) tend to be rounder, and thick and woolly with a very crinkled surface.
Cats dislike the smell of rue, lavender and pennyroyal, Coleus canina and lemon thyme. Plant a few of these throughout the garden. (Interplanting can attract pollinators and other beneficial insects too.) Cats steer clear of strong citrus scents.
According to the ASPCA (American Society for the Prevention of Cruelty to Animals), lavender is toxic to cats when ingested. The primary toxins, linalool and linalyl acetate, can cause gastrointestinal upset and more serious conditions if consumed in significant quantities.
Again it is imperative to contact your veterinarian for proper care of your pet. Toxic to both cats and dogs are Tulips, Azalea, Bird of Paradise, Aloe, Begonias, Baby's Breath, and Amaryllis. Members of the Lilium genus, including Easter and stargazer lilies, can cause serious kidney problems if ingested by cats.
All species of Datura are extremely poisonous and psychoactive, especially their seeds and flowers, which can cause respiratory depression, arrhythmias, fever, delirium, hallucinations, anticholinergic toxidrome, psychosis, and death if taken internally.
Hallucinogens. Dozens of hallucinogenic plants are used recreationally around the world. In the United States, the most popular hallucinogenic agents are mescaline (from the peyote cactus), psilocybin and psilocin (from several mushroom species), and the synthetic ergot lysergic acid diethylamide (LSD)/β.
DMT is naturally occurring in small amounts in rat brains, human cerebrospinal fluid, and other tissues of humans and other mammals.
