I have a 3 year old female ( fixed ) that have had since she was 5 weeks old ( she has feline herpes also ) Now we have rescued a male cat had him fixed ( 3 weeks ago ) we are trying to get them to like or at least put up with each other...the female male cat hisses, growls and snorts and throws a fit...we have been keeping them apart and have the male on porch and they see each other thru the glass door which we open a crack so they can smell each other and even sticks their paws thru...it's been three weeks and they hate each other...or at least the female hates him.....HELP
