Ayo so my thing was over 250 characters so ima comment more with this instead:
The first cat is Cali.This is her first(and her forever)home.I was C's favorite of my family and she would spend nearly all of her time in my room.Around a 1yr and a half ago,we got another cat,named Ali.When A was a kitten C would groom her,but A was also very playful and would annoy C by playing with her.This was normal, I thought, and it'll pass as A matures and grows out of that phase.A grew to like me a lot and she began spending all of her time with me in my room,Now it is A that spends all of her time in here,and C cannot stand her. She can't stand even knowing that shes at my door,and will growl.I know that C is jealous of A.She will sniff at my room and growl like she is smelling A.She will growl at me at times now if I try to keep her in my room and pet her alone.A never hisses/growls at C,just lightly swats at her when she is swatted at.
