Is 'Cavolo Nero' Kale toxic to cats?

No — 'cavolo nero' kale 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. Kale (a Brassica oleracea cultivar) is not on the ASPCA toxic-plant list; the ASPCA classes it among the cruciferous vegetables safe for dogs and cats in small amounts. Note that raw kale acts as an oxidant and large quantities can contribute to gas, GI upset, goitrogenic effects or Heinz-body anaemia, so feed only sparingly and cooked.

Yes — the ASPCA lists 'cavolo nero' kale 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.

The ASPCA classification Growli uses applies to both cats and dogs: 'Cavolo Nero' Kale is non-toxic to dogs as well. See the full 'cavolo nero' kale pet-safety guide for both species.
