The woolly foliage may cause mild mechanical irritation if chewed in quantity, but no systemic toxicity is reported. Considered safe for dogs and cats.

Yes — the ASPCA lists columnae snow-in-summer 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.
