A teabag/bat?

Got up this morning and went into the kitchen to fill the sink.
Noticed that NS had used rather a lot of teabags and reached in to squeeze them and chuck them in the bin.
You know that split second when you touch something and it's not how it should feel? Well these tea bags weren't squishy and wet they were soft and furry and MOVED!
Scream is not a word I use lightly!
Anyway, gathered this bat up in a tea towel and put him outside on top of the well out the back. He's still there and alive.
The question is how did he get into the kitchen? The sink? What a mystery!
Been washing my hands a lot today. They carry ecoli and rabies.
