Satin
Pothos.

What it does to a cat.

Yes — satin pothos is toxic to cats. The ASPCA lists Scindapsus pictus (satin pothos, also sold as Silver Pothos, Silver Philodendron, or Silvery Philodendron) as toxic to dogs, cats, and horses. All parts contain insoluble calcium oxalate crystals that embed in mouth and throat tissue on chewing — immediate burning, drooling, and often vomiting.

The ASPCA verdict, verbatim: Toxic to Dogs, Toxic to Cats, Toxic to Horses · Family: Araceae · Additional Common Names: Silver Pothos, Silver Philodendron, Silvery Philodendron · Scientific Name: Scindapsus pictus · Toxic Principles: Insoluble calcium oxalates · Clinical Signs: Oral irritation, intense burning and irritation of mouth, tongue and lips, excessive drooling, vomiting, difficulty swallowing.

Satin pothos is not the same plant as golden pothos

This is the single most important disambiguation on the page. Two plants share the "pothos" trade name:

• Satin pothos (this page) — Scindapsus pictus, silver-flecked heart-shaped leaves with a matte velvety finish. Smaller leaves, finer trailing vine. Genus Scindapsus.
• Golden pothos — Epipremnum aureum, larger glossy yellow-streaked leaves on thicker stems. The plant most people mean by "pothos." Genus Epipremnum. See our pothos page.

The ASPCA has two separate entries because they are genuinely different genera. From a botanical perspective the distinction matters. From a cat-household perspective it does not — both are Araceae, both produce raphide crystals, both will cause the same oral irritation if chewed. If you own either one, treat it the same way.

Same toxin family as peace lily and philodendron

Calcium oxalate raphides are the signature Araceae weapon. The mechanism is mechanical-chemical: needle-like crystals release on chewing and embed in mouth and throat tissue, with associated proteolytic enzymes amplifying the irritation. Same story as peace lily, philodendron, monstera, and dieffenbachia. Cats present near-identically across the whole group: minutes-to-onset pawing, drooling, sometimes vomiting, occasionally airway swelling.

Safe trailing swaps

If you want the trailing-vine look without the oxalates, the cat-safe options are:

• Spider plant — arching pups, non-toxic per ASPCA, easiest safe trailer.
• Wax plant — thick waxy leaves, porcelain flowers, slow-growing trailing vine.
• Swedish ivy — soft cascading stems, similar shelf role to satin pothos.
• Burro's tail — succulent trailing form for sunnier spots.

None of these have the exact silver-fleck pattern of Scindapsus pictus, which is genuinely distinctive. But all four fill the same trailing-from-a-shelf role with no calcium oxalate risk.
