It was chaotic last night. Collected boy, took him to karate club, then went into town for new school shoes, got caught in rush hour traffic, didn't get home until late. Just had time to feed boy and then it was his bedtime.
In all that rush I didn't get out to shut the shed door which we shut every night due to foxes in the area. It was left open all night. And this morning I have no guinea pigs.
I am a stupid idiot.
