Is 'Romanesco' Broccoli toxic to cats?

No — 'romanesco' broccoli 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. Brassica vegetables (broccoli/cauliflower) are not on the ASPCA toxic-plant list, and the ASPCA Animal Poison Control Center lists broccoli and cauliflower among safe snack vegetables for dogs and cats in moderation. Large quantities can cause gas, GI upset and goitrogenic effects, so keep to small, occasional portions.

Yes — the ASPCA lists 'romanesco' broccoli 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: 'Romanesco' Broccoli is non-toxic to dogs as well. See the full 'romanesco' broccoli pet-safety guide for both species.
