Is Calabrese Broccoli toxic to cats?

No — calabrese 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. Broccoli (Brassica oleracea) is not on the ASPCA toxic-plant list and is widely regarded as non-toxic to cats and dogs; the ASPCA even lists broccoli among foods that can be shared in moderation. As a brassica it contains isothiocyanates, so large amounts can cause GI irritation and gas; keep it to small, occasional portions rather than a staple.

Yes — the ASPCA lists calabrese 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.
