So I've had my two cats for around 5 years now. (5y.o/F) and (3y.o/F), the 5y.o had a brother that passed away a year after they were born before the 3y.o came along a year after that. They don't hate each other per se, the 3y.o is a very affectionate cat but the 5y.o just tolerates her, she refuses any affection from her beyond nose sniffing and will occasionally hiss at her if she takes her spot on the window. The 5y.o has always been a reserved cat that only gets cuddly around me so I'm not sure if I should let them be or try to improve their behavior? If so, is there any method to get them to like each other? All the other posts focus on cats getting along or not hissing
