Vinca
Periwinkle, Running Myrtle
Vinca rosea
Apocynaceae
Vinca is an annual flower that blooms continuously and tolerates heat and humidity well. Europe, northwest Africa, and southwest Asia are all home to this species. They have one to two-meter-long slender trailing stems. Vinca stems frequently take root where they come into contact with the ground, allowing the plant to spread widely. Their leaves are commonly simple, lanceolate to ovate shaped, and alternating. Vinca alkaloids are the substances found in vinca plants that are toxic to animals, particularly to cats. When felines consume a portion of the vinca plant, they may suffer from symptoms such as vomiting, diarrhea, low blood pressure, depression, tremors, seizures, and coma, which can further lead to fatality.

Virgin’s Bower
Clematis, Leather flower
Clematis sp.
Ranunculaceae
Virgin's bower is a  deciduous perennial vine that can be found in the eastern United States and Canada. It commonly grows in damp lowlands, thickets, and forests, particularly near streams and ponds. The Virgin's Bower vine grows easily on natural materials such as trees and plants. It can also spread along the ground's surface, generating a dense canopy of leaves. Virgin's bower has protoanemonin which are glycoside irritants that are toxic to cats. If ingested, cats may show poisoning symptoms such as excessive drooling, vomiting, and diarrhea.

Wahoo
Burning Bush, Spindle Tree
Euonymus occidentalis
Celastraceae
Wahoo is a shrub that is native to eastern North America and belongs to the bittersweet family. It's an eight-meter-tall deciduous shrub with stems up to ten cm in diameter. It has thin, dark purplish-brown twigs that are sometimes four-angled or somewhat winged, with gray, smooth, and gently fissured bark. Alkaloids and cardenolides are the toxins found in wahoo plants. Ingesting this plant may cause negative effects in cats. It can induce symptoms such as vomiting, diarrhea, abdominal pain, and weakness. Heart rhythm abnormalities are also possible if the plant is eaten in large doses.

Wild Carnation
Carnation, Sweet William, Pinks
Dianthus caryophyllus
Caryophyllaceae
Carnations in the wild have a more streamlined appearance than their farmed counterparts. They are little plants that produce flowers with five serrated petals in a variety of colors ranging from white to pink. The male parts of the flowers mature and senesce before the female parts, making them protandrous. They prefer moist, well-drained gritty soils heavy in organic content, as well as colder summer conditions. The toxicity of wild carnations comes from unknown irritants, which produce symptoms including minor vomiting and diarrhea, as well as mild dermatitis in cats.

Wild Coffee
Geranium-Leaf Aralia, Coffee Tree
Polyscias Guilfoyle
Araliaceae
Wild coffee is a slow-growing tropical plant that is often used as an ornamental in Southeast Asia. When kept indoors, they can be clipped to preserve the proper size. They can reach a height of six to eight feet if not pruned. Wild coffee leaves might be variegated with white or yellow edges or totally green. They normally shed their leaves when the temperature dips below 50 degrees Fahrenheit. If ingested, saponins in wild coffee can irritate a cat's skin and cause inflammation in his mouth and gastrointestinal tract. Skin rashes, vomiting, loss of appetite, fatigue, and an increased heart rate are some of the symptoms of coffee tree poisoning.

Wisteria

Wisteria spp.
Fabaceae
Wisteria is a flowering plant genus native to Asia, North America, and portions of Iran that belongs to the Fabaceae family of legumes. Wisteria climbs by twining its stems around any available structure. The leaves are pinnate, alternating, and have nine to 19 leaflets. The blooms are produced in pendulous racemes that range in color from purple to violet to pink to white. Lectin and wisterin glycoside are the toxic elements found in wisterias. Cats may experience symptoms such as vomiting, diarrhea, and depression after ingesting a part of wisteria.

Wood Lily

Lilium umbellatum
Liliaceae
Wood Lily is a perennial lily species native to North America that grows up to three feet tall on a single stem. Around the stem, the leaves form a whorled pattern, and the top of the stalk can support up to five flowers. The wood lily's blossoms are what make it such a popular plant. The six independent flared petals of the bright orange cup-shaped blooms are marked with deep purple dots right at the base. While the toxic properties of wood lilies are unknown, cat owners should keep their cats away from them because they can cause severe and fatal symptoms. Vomiting, inappetence, lethargy, and kidney failure are some of the symptoms of your cat eating a piece of a wood lily.

Yellow Oleander

Thevetia peruviana
Apocynaceae
Yellow Oleander is a tropical evergreen shrub or small tree native to Central America. It has willow-like leaves that are linear-lanceolate and glossy green in color. It has a green stem that turns silver or gray as it ages. The long funnel-shaped, sometimes-fragrant yellow flowers grow in terminal clusters of a few flowers. Cat owners should be aware that yellow oleander is poisonous to cats. Yellow oleanders contain cardenolides, which are highly poisonous. These chemicals can cause vomiting, diarrhea, and a sluggish heart rate in cats, according to the ASPCA Animal Poison Control Center.

Yew
Japanese Yew
Taxus spp.
Taxaceae
Yew, also known as Japanese Yew, is a large evergreen tree or shrub native to Japan, Korea, and parts of China. This tree can reach a height of 10–18 meters and has a trunk diameter of up to 60 centimeters. Yew leaves are lanceolate, flat, dark green, and spirally arranged on the stem. Taxines are the toxic component found in yew. These poisonous substances can be found in the plant's leaves, seeds, and stems. When cats are exposed to this substance, they may develop symptoms such as muscle tremors and dyspnea. If not treated immediately, it can cause acute cardiac failure and eventually death.

Yucca

Yucca spp.
Agavaceae
Yucca is a genus of Asparagaceae perennial shrubs and trees. Its 40–50 species are distinguished by their evergreen rosettes, tough, sword-shaped leaves, and large terminal panicles of white or whitish flowers. They are native to the Americas and the Caribbean, where it is hot and dry. Yuccas are commonly grown in gardens as ornamental plants. Many species produce edible parts such as fruits, seeds, flowers, flowering stems, and, in rare cases, roots. Yucca is considered toxic to felines as it contains saponins. Saponins are naturally produced substances that serve as the plant's protection. However, when ingested by cats, it may cause them to experience symptoms such as vomiting, hypersalivation, loss of appetite, diarrhea, and weakness.
