Bisexual Cat

So we have been having issues with this male Siamese that's been bugging Sweep.



For the past month or so our neighbor below (who has a 8-9 month old female kitten) has been been complaining about this Siamese cat that comes around usually at about 5 am and makes this deep, gut-wrenching wail/meow/growl at their cat, Ali (apparently short for Alicia...*shrugs*) that wakes us up as well. Apart from the nightly noise, this Siamese throws himself against their screen door as well making this crashing noise which can get a little worrying...and we put it down to their need to mate, what with spring/summer in the air.

So imagine my surprise when 4 days ago, Sweep who's quite calmly looking out the window, suddenly tenses and starts thrashing his tail...not quite a violently as when he sees a bird outside...and then bounds towards the door for a better look.

Curious, we looked out the window to see the same Siamese equally calm, staring at Sweep and sitting there and doing the same deep, gut-wrenching wail/meow/growl *shrugs* We are convinced the Siamese is bi-sexual...
