With covid going on we have not had many visitors to the house, this kitty being the exception. For as long as we have had kitties they have had visitors. They mostly just stare at each other but their tails are not always in the air (a cat with its tail straight up in the air means that are willing to be sociable with other cats).
We (the humans in the family) also appreciate the visitors since the scent of a cat will keep squirrels away from digging up Moms bulbs in the garden.
