We've got 2 cats at home at the moment, both neutered. Our cat is a male ~9-10 months old and my brother brought his for the summer, which is a female ~11-12 months old.
They've met before and during those encounters our male was arching his back and hissing, but she is generally relaxed, not paying him much mind from the looks of things (or she could be distracted by her surroundings). He has displayed territorial behavior since she is placed in my brother's room, with him, which is normally open and vacant when my brother isn't staying here and the male likes to sleep in that room.
Here's the question though: When they notice each other from under the door, they'll both be glued there trying to poke at each other under it. There is no hissing, no aggression (our male gets aggravated if he's disturbed but it isn't hard to distract him, unless the female is meowing). We can't tell if this is playing or hunting and we can't tell if they understand who's on the other side.
- is it reasonable to assume they know there's a cat on the other side?
- is it reasonable to assume they know which cat is on the other side, since they do sniff under the door occasionally?
- is it reasonable to assume they haven't yet associated each other's scent and identity to their appearances?
and of course
- is it possible to get them to identify each other if they can get close enough to get a scent? (they have been close but only once and the male was aggressive while the female was in her cage)
Thanks and sorry for the wall of questions.
edit - followup question here
