Is kidney-leaved bladderwort toxic to cats?

No — kidney-leaved bladderwort 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. Utricularia reniformis is not individually listed by ASPCA as toxic or non-toxic. No toxic compounds are documented for the genus Utricularia. The bladder trap mechanism is specific to microscopic aquatic and soil invertebrates and poses no risk to cats or dogs. Considered safe in pet-inclusive households.

Yes — the ASPCA lists kidney-leaved bladderwort 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.
