Mexican Feather Grass

No toxicity claim found from either ASPCA or NC State Extension for this species. The more significant flag here is horticultural, not toxicological: see the invasive-status note below above. A more mechanical, non-toxicity caution worth passing along regardless of pet species: the seed heads' stiff, sharp awns can work into skin, fur, eyes, and ears the way foxtail grass awns famously do for dogs, though that specific claim is not confirmed for this species by name: flagged as a general awned-grass caution, not a sourced fact about this species specifically.
