Are they cat proof.

Rich, thank you for your question. The Trim+Go faux wood blinds would be the better option for blinds in a home with a cat. The faux wood slats are thicker and heavier than the slats of a traditional vinyl blind that tend to crack and break. And of course being a faux wood slat instead of a cloth or fabric shade there would be minimal damage from claws. Mine have held up well in the home with cats. - Kimberly
