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.
