We got two kittens from the animal shelter: 12 weeks old, pitch black, and undomesticated.
Their adjustment to our household is wonderful to watch.
Day one: as soon as they have the chance, they escape from the cage in which they came and find their own hiding place. We discover it behind the piano.
Day two: overnight they have used the litter box and eaten their food. Good guys! Still in hiding. When we are not in the room they skulk around.
Day three: the braver of the two is making reconnaissance trips into the new territory while I am in the room. I throw a cork that needs investigating. However, not while that big animal is around.
To be continued.
