Are Rat Terriers good with cats?

Yes, Rat Terriers can be good with cats, but early and proper socialization is key, as the breed’s prey drive is high, and their instinct is to chase smaller animals. Of course, each dog (and cat) has their own preferences and temperament, but you can feel fairly confident your Rat Terrier, if properly socialized to your cat and introduced at a young age, should get along just fine.
