Common questions

Does goldenrod cause allergies that could bother my cat?

Goldenrod pollen is heavy and insect-carried — ragweed is the real hay fever culprit. Allergy is not the issue; only gut upset from eating it is.

Is goldenrod tea safe if my cat shares a lick?

A lick is harmless. Avoid sweetened or milk-containing preparations, which are the actual concern.
