Even the juveniles will start hissing and showing teeth if you walk up on it. We had lots of experience last year - 12 over a 2 week period. I got to the point where I'd constantly get up in the night to check, even after we put out a live trap.I think the lack of response was likely due to it being in the middle of eating. It had something it was munching on. I think it was irritated that the guinea was disturbing it, but maybe due to other run-ins knew the guinea wouldn’t give up?
Perhaps if it was just a young one it might not have known how to respond. I’m really not
We had a mom w/3 babies, then varies stages of "teens". They were all cute until they saw us.
The last one, there was nothing cute about it. It was much bigger & older. I thought for sure he was going to break the trap; he managed to flip it over on it's side but still didn't get out.
I don't know what the magic was after the 2 weeks in June, if they'd been driven out by construction somewhere or they recognized the smell of blood, but there weren't any after that.
