Is Yellow Gentian toxic to cats?

Mildly. The ASPCA lists yellow gentian as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. Gentiana lutea is not individually listed by the ASPCA. The plant contains concentrated bitter iridoid glycosides — particularly gentiopicrin and amarogentin — that give it its medicinal bitterness and may cause gastrointestinal upset (vomiting, diarrhoea) in pets if ingested. Treat as mildly toxic. Note: the leaves closely resemble toxic Veratrum album (white hellebore) — correct identification before cultivation is safety-critical.

Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your cat has had access to yellow gentian.

Stay calm. Remove any plant from your cat's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.

The ASPCA classification Growli uses applies to both cats and dogs: Yellow Gentian is mildly toxic to dogs as well. See the full yellow gentian pet-safety guide for both species.
