Well yeah I think at those blinds and he's going for a win, I think he can call . It looks like there's a 11K pot and he's calling about 2K? He's low if he folds and he's not out if he loses.
Not sure what the flop cards are but if his outs are good he can call.

Hadn't seen the other replies but yeah that's a good point Blackinks.
So he had trips and lost I see. I think you did the right thing Cat and he shouldn't moan at you
