Are Feists good with cats?
No, Feists aren’t good with cats as a baseline, as they have a high chase and prey drive. They’re bred to chase and then bark at treed animals, so they may be prone to chasing your cat up a tree or onto a perch indoors and then barking at them, which, of course, would likely be very stressful for the kitty. 
With early socialization and positive reinforcement training, Feist dogs can be good with cats, but consistent training, lots of supervision, and providing safe outlets for your pup to get out their desire to chase (such as with fetch and flirt poles), are key to increasing the chances of a peaceful relationship. 
If you plan on adopting an adult Feist without a known history of being calm with cats, it’s best to introduce your kitty and the potential adoptee first to assess the pup’s reaction before committing to adoption.
