I Don'T Know Outside

I don't know outside Having never been The couch is my lair Along with the bed I sit on the sill And stare at the scene Feathered shapes Flit around so fast Are they real? I can't tell there's no smell So I guess not I chase a red dot That catches my eye Then I eat and lie down I sometimes sense more But not sure what could be My life goes on I get my treats and Wonderful scratches Just where I need them
