I have two cats. Nylo is a four year old male, and Phoenix is a two year old female. Phoenix has lived with us for about two years now...we got her as a kitten. From the start, Nylo has been very welcoming. However, earlier today, Nylo was lying on the arm of the couch, nearly asleep, when Phoenix came up and sniffed his paw. Nylo swatted at her...Phoenix walked away with no issue. Is it common for cats to have little spats like this? I'm probably overthinking things...just want to stay on top of it.
