<human>: I posted a few weeks ago about an incident where a stray cat walked into my apartment one night when I left the back door open. The stray cat and my cat were fighting when I woke up in a daze. I shooed the stray out, and it left my cat in a weird state where he would growl. Fast forward to the next morning, and he was fine, but he had a little limp from the fight. It was very clear that my cat built a deep hatred for the stray.

Over the course of time, the stray would come to my back porch behind the glass and my cat would just go nuts hissing and just acting completely out of the ordinary. Fast forward to last night and the stray found it's way to my back porch. I go to try and calm my cat down and shoo the stray away and my cat attacked me! He never has attacked anyone other than his little play mice and toys, and such. 

I guess he went into a state of panic, but he definitely got me good. He has all his claws and has this nifty scratching post, so I guess they keep his claws strong and sharp. He even tried to go at my leg one other time until I just let him do his thing and didn't bother him. He is a super friendly cat, but my thoughts are that this stray kind of messed with him a bit. 

He was fine about 20 mins after the incident occurred. Almost like nothing occurred. He was fine this morning and when I stopped by for lunch.

This is just so odd because he has been the most even keeled cat in the 5+ years I've had him.

Just curious what you guys would do in this situation? I sprayed some of that bitter apple stuff around my back porch perimeter and also called the apartment company to see what their protocol is.

Give me the gist of the text in a nutshell
<bot>: A stray cat keeps coming to my back porch and it messes with my cats mind. How do I get rid of said stray cat?
