Could this be Betty's brother?

Every day as part of my rounds I swing by the eastern colony in the portlands that I started working on last fall, home of rescued cats Betty, Lini and Winston.  Recently this tabby has been waiting for me and meowing at me and letting me pat him.

Clearly a male, he was fighting with an orange cat, so you know what comes next, yes, neutering.  I showed up Monday and there he was.  I set up the trap and he went in five minutes later.  Once in, though, he decided it was a bad idea, and poor guy thrashed around.

He was neutered yesterday and went to Raven's for recovery and assessment.  Within half an hour, she emailed me to say look for a foster home!

I wonder if he is Betty's brother, they are the same age, and Raven thinks the same temperament. Raven had Betty briefly at her place and pronounced her amazing, which she is I must say.  I don't think I've ever seen a cat who seems so happy.  I hope this guy adjusts as well to living inside.
