Is straight-leaved butterwort toxic to cats?

No — straight-leaved butterwort is listed by the ASPCA as non-toxic to cats. It is a sensible choice for a home with a cat; a curious nibble will not poison them, though no plant is meant to be eaten. Pinguicula is not individually listed by ASPCA as toxic or non-toxic. The digestive enzymes on the leaf surface are adapted for small invertebrates and are not known to be poisonous to cats or dogs, but nibbling should be discouraged as gut irritation is possible. No toxic alkaloids or glycosides are reported for this genus.

Yes — the ASPCA lists straight-leaved butterwort as non-toxic to cats and dogs. A cat that chews a large amount of any foliage can still get a mild, brief stomach upset, so discourage grazing, but it will not be poisoned.
