Common questions

Can my cat eat sunflower seeds?

A plain, unsalted seed or two is safe, but cats gain nothing from them and the shells are indigestible — there is no real reason to offer them.

Are sunflowers safe in a cut bouquet?

Yes — sunflowers are one of the safest bouquet choices, unlike lilies which should never enter a cat household.
