|Siri seemed very interested in someone/something on the deck at the side of the house.|
|It's Neighbor Cat's sister!|
Next Door Neighbor Lady told me that Neighbor Cat has a sister, a litter mate, who recently escaped their house, apparently preferring the outdoor life (like her sister). I would never have guessed that they were litter mates, because they only resemble each other in color. The sister has long hair, whereas Neighbor Cat has short hair.
I'm not sure what the attraction is here - they have two dogs, I have two dogs (although mine seem to be a little bit calmer). Maybe the cat is just looking for some peace and quiet, or maybe they like hunting in the cemetery next door.
