Every-day friction, fixed

Built around how cats — and cat owners — actually live.

No gimmicks. Every product exists because of a specific, recurring annoyance.

Renter-friendly

Suction mounts mean no drilling, no wall damage, and no landlord conversations.

Small-space smart

Window-mounted comfort gives your cat more territory without you losing floor space.

Not just for windows

Glass, marble, tile, metal, painted panels — our suction mounts hold on nearly any smooth surface.

Why we started this

One cat, one sunny windowsill, one idea.

We started Whisker & Sill after watching our own cat fight for the one warm spot on the windowsill every single day. Nothing out there avoided drilling, and nothing felt genuinely cozy instead of just functional. So we made one. For every order, $1 goes directly to local cat shelters.
