New dog stiffens up and barks at cats with barrier, do I take down barrier and leave her on leash and let her bark it out and reward her for ignoring them/not barking at them?

14 days in with new dog. She’s been great so far, goes potty when she should (besides when it was -20° and she didn’t have snow pants yet) she’s been doing great with basic training/commands and doesn’t bark at anything besides the cats. we’ve been rotating the cats and the dog from our bedroom to the whole house so they haven’t really been together yet besides trying interaction behind a gate but I feel like she might have barrier anxiety maybe? Not sure where to go from here, if it lasts much longer without progress we will get professional behavior training but would like to avoid that. They don’t need to be friends but I can’t have the dog barreling through the house chasing them and scarring them. Any help appreciated, thanks.
