Find your cat's favorite spot in the house.
Thoughtfully designed perches and comforts that turn any window into your cat's whole personality. No drilling, no fuss, no more fighting over the sunny spot.
Real problems, solved. One happier cat.
Everything in the Whisker & Sill lineup is picked for one reason: it fixes something you deal with every day.
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.
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.
What sets us apart
Real cats. Real windowsills.
"Mounted it in ten minutes and my cat was up there before I even put the tools away. She hasn't slept anywhere else since."
"Sticks to the glass perfectly and holds my chunky boy with no problem. The pom-pom trim is even cuter in person."
"Renting an apartment with one sunny window — this hammock has become my cat's whole world."
