Laz Screwed Up Yesterday

It wasn't a great day yesterday.  In the morning, Laz suddenly decided to  attack Ayla when she dared to come out of the bedroom.  He had been good for days, so both she and I hoped he was getting used to the house.   And I thought that the outside time of the past few days was calming him down.  

He got to run around, explore, discover new things, wander around with Marley, etc...

No such luck.  He suddenly lit into her RIGHT AT MY FEET.  Forgive me, but I had to kick him to get him to stop!  And he went right after her again!  She ran for the bedroom with him right behind her.  I followed.  She hid.  

And he had the nerve to look back at at me like "what's wrong".  I comforted Ayla.  No wonder she is peeing on the bathroom mat and in the toilet.  She dares not go down to the litterboxes.

Laz follows Marley around outside.  When they tussle inside or out, he tussles friendly.  I don't know why.  Maybe he tussled rough and Marley beat the crap out of him...  But Ayla can't do that.  She is becoming terrified of him.

I've been patient and attentive to Laz.  I know he had a hard start in life and I've treated him carefully and gently.  But basically, he is a mean bastard.  I don't know what to do.

And yesterday afternoon, when I let him out with Marley, things seemed fine.  At one point I briefly went out front to get the mail.  When I came back in, he was in the neighbor's yard.  He jumped the fence.  And he was crying and calling.  Well, there is a spot where a cat can can halfway up so getting UP is easy.  and getting down is easy.  Getting BACK up is harder.

I got him to follow me back and forth near the fence.  He tried to jump up but couldn't.  I finally unscrewed a fence board off so he could walk right through.  Would he?  NO!  Not will I was there.  He doesn't respond to whistles, clicks or any sound I make.  After 5 months, he doesn't recognize his name or even "dinner".  I practically have to shove a bowl under his nose.

He came back through the removed fence board only WHEN I wasn't there.

Laz needs to be an "only cat".  And I think an indoors cat.

He is GREAT around ME!  Flops down in front of me and requests scritchies.  Never suggests using a claw.  Likes me a lot.  And for himself, I like HIM.  He just can't be around other (or maybe just "smaller") cats.  

I have never given up on any cat in my life before, but I am beginning to now.  Maybe I'm just depressed, but this is not working out.  Laz needs a different home and I feel like such a damn failure saying that.

Any suggestions?
